ShopGoodwill Tips: What 473,000 Auctions Show About Winning
Most ShopGoodwill advice is a list of habits: snipe at the last second, bid on Sunday nights, watch out for the store bidding on its own items. We checked those habits against about 473,000 closed auctions from 157 Goodwill locations, Sep 24 to Oct 28, 2026, with 3.35 million bids between them.
The short version: where an item is listed matters more than when you bid. Relisted items sell for less. Bidding in the last hour helps, but the last second does not. And the shill bidding story does not hold up.
The tips at a glance
| Tip | What the auctions show |
|---|---|
| Shop the cheaper locations | The cheapest tenth of locations sell about 18% below average, the priciest tenth about 26% above |
| Watch for relists | About 6% of won auctions come back about 10.5 days later and sell 11 to 14% cheaper |
| Bid in the last hour | Winners who first bid in the final hour paid about 8% less |
| Skip the last-second snipe | The final 10 seconds did no better than 10 to 60 minutes out |
| Ignore the day and time | Sunday night endings moved prices by less than 1% |
| Don’t blame the store | 5 of 6,735 bidder and location pairs looked like shills, and they pushed prices down |
Cheapest ShopGoodwill locations
Location made the biggest difference of anything we measured. To compare locations fairly, we built a price index from like-for-like auctions: the same category at the same starting price, with 1.00 as the average across all locations. A location at 1.61 sells the same kind of item for about 61% more than average. A location at 0.69 sells it for about 31% less.
| Location | Price index |
|---|---|
| Baltimore | 1.61 |
| West Palm Beach | 1.45 |
| Hamden, CT | 1.35 |
| Tampa | 1.31 |
| Santa Rosa | 1.27 |
| San Diego | 1.25 |
| Houston | 1.23 |
| Average location | 1.00 |
| Honolulu | 0.79 |
| Pasco, WA | 0.79 |
| Tucson | 0.76 |
| Greensboro | 0.71 |
| Bowling Green, KY | 0.69 |
| Lexington, KY | 0.69 |
This is the same kind of item, not the identical item. Two “film cameras” auctions with the same starting price can still hold very different cameras. Across thousands of auctions the comparison is fair, and the ranking held week to week.
It is not cost of living. Anyone can bid at any location, so a Baltimore listing competes for the same national pool of buyers as a Lexington one. The difference is attention: the pricier locations drew about 5.5 to 6.5 bidders per auction, the cheaper ones about 4 to 4.5. More bidders push the final price up.
If you only watch one or two large locations, you are likely paying their premium. Search across all locations, and save searches for the categories you buy instead of browsing one store’s listings.
How to win ShopGoodwill auctions: timing and sniping
Waiting until the final seconds is the most common ShopGoodwill tip. The auctions say it is half right.
- The last hour matters. Winners who placed their first bid in the final hour paid about 8% less than similar auctions. Winners who got in days earlier paid about 10% more. An early bid tells everyone else the item is worth watching.
- The last second does not. Within that final hour, bids in the last 10 seconds did no better than bids placed 10 to 60 minutes before the close.
- Most “bidding wars” are not wars. About 13% of the final price gets added in the last minute, but most of that is the price catching up to a maximum bid someone placed earlier. A true late bidding war happened in 7.7% of auctions.
The practical version: decide your maximum, enter it once in the last hour, and leave it. You get the benefit of a late bid without needing to time the final seconds.
Best time to bid on ShopGoodwill
Day and time barely matter. Sunday night endings, often called the most competitive slot, moved final prices by less than 1% compared with other times. Your time is better spent choosing the location and the relist than the clock.
ShopGoodwill relisted items sell for less
About 6% of won auctions, roughly 1 in 17, come back as a new listing. They return about 10.5 days later on average, and the timing is regular enough to point to the usual cause: the winner did not pay before the deadline.
| Winning price | Share that came back as a relist |
|---|---|
| Under $20 | About 3% |
| All won auctions | About 6% (1 in 17) |
| Over $100 | About 10% (1 in 10) |
Expensive items come back more often, which is where it pays to watch. Two details for buyers:
- Relisted items sold for about 11 to 14% less than the first time.
- If you were the runner-up on the original auction, you won the relist about 6% of the time, 5 to 8 times more often than chance, usually for about 20% less than the original winning price.
If you lose a higher-priced item, save it and check the same location about a week and a half later.
Is ShopGoodwill shill bidding real?
A common complaint: a name you have never seen bids you up a few dollars at a time, then the item shows up again a week later. The usual theory is that the store is bidding on its own items.
ShopGoodwill masks bidder names to the first and last character, so one masked name can be many different people. We looked for masked names that behave unusually at one location compared with everywhere else. Of 6,735 name and location pairs with enough history, 125 set the final price more often at one location than expected. Only 5 matched the shill pattern of repeatedly setting the price and rarely winning.
Those 5 did the opposite of what a shill would do. Items they bid on sold for 36% to 74% of what similar items normally sell for. They were bargain hunters placing one low bid on hundreds of items. The heaviest bidders on the site bid at more than 100 locations, which does not fit a store employee.
What we could not rule out: retracted bids do not show in closed auctions, so “bid it up, then pull out” would not be visible, and a shill using a very common masked name would blend in. But the simple version of the story is not in the data. The person outbidding you is far more likely another reseller.
Sourcing from ShopGoodwill for reselling
For resellers, the buy price is the margin. Put the findings together and a sourcing routine looks like this:
- Search across all locations. The price index is the largest lever we found. The same kind of item from a 0.70 location instead of a 1.30 one can be the difference between a flip and a pass.
- Track relists in your price band. Above $100, about 1 in 10 won auctions comes back, cheaper.
- Bid once, late. Enter your maximum in the last hour. Do not bid days ahead.
- Know who you are bidding against. Some categories have a regular. One masked name wins about 19% of video game auctions. Others, like cameras and records, are spread across many buyers. Specialists are not getting steals, though: they pay about the same as everyone else, sometimes more.
- Price in shipping. Shipping is calculated at checkout on most auctions and was not part of these prices. On heavy items it can erase the location discount.
You can see which masked names win each category on our ShopGoodwill category specialists page, for example cameras, records, video games and LEGO. You can also search a username to see its masked form.
If you resell from retail too, the live deal feed shows current price drops and clearance across Home Depot, Lowe’s, Walmart, Best Buy, Costco and other retailers, and the guide on where to sell clearance finds covers the selling side.
What this data does not cover
These are closed auctions from Sep 24 to Oct 28, 2026, so seasonal patterns beyond five weeks are not included. Shipping costs and retracted bids are not part of the numbers. Masked names let us show patterns, not identify who is behind them.
Frequently Asked Questions
How do you win auctions on ShopGoodwill?
Enter your maximum bid once in the last hour of the auction, look across all Goodwill locations instead of one or two large ones, and watch for relisted items. Winners who first bid in the final hour paid about 8% less than similar auctions, while winners who bid days earlier paid about 10% more.
Does sniping work on ShopGoodwill?
Partly. Bidding in the last hour helps, but bidding in the final 10 seconds did no better than bidding 10 to 60 minutes before the close. A true last-minute bidding war happened in 7.7% of auctions.
Does ShopGoodwill shill bid?
The data does not support it. Of 6,735 bidder and location pairs, only 5 matched a shill pattern, and items they bid on sold for less than usual, not more. Retracted bids are not visible in closed auctions, so that case cannot be fully ruled out.
