Can I sell items I bought before joining Croissant?
Yes! You don't need to have bought an item through Croissant to sell it. If you already own something from a partner retailer, you can import it into your Collection and sell it to Croissant for credit. The easiest way is Gmail Sync, which finds your eligible past purchases automatically. (Shopping with the extension active is still the best way to earn credit back going forward — Gmail Sync is for things you've already bought.)
Import with Gmail Sync
Gmail connects in the Croissant app. On croissant.com, you start from the site and the page hands you off to the app.
In the app
Tap the ⋯ menu at the top right of your Home screen ①.
Open Account Management ②.
Under Synced Accounts, tap Get Started ③ and follow Google's steps to securely connect your Gmail. Once connected, eligible purchases import automatically with resale values — watch your Collection grow. (If you've already connected an account, the button reads Link Another Account.)
On croissant.com
Choose Your account at the bottom of the left menu and find Gmail. Click Connect Gmail ① (it reads Connect another inbox if you've already connected one).
On the page that opens, scan the QR code ① with your iPhone camera to open Connect Gmail in the Croissant app, then follow Google's steps there.
Once Gmail is connected, the page counts the pieces it finds as your import runs — usually about 30 seconds — and then shows See your collection. If your collection is empty, Overview under Collection also has a Connect Gmail link.
Your privacy:
Croissant only looks for receipt emails from our supported brands and retailers, and doesn't store or access anything beyond what's needed to import your items with accurate details.
Already synced but not seeing new items? Re-sync — in the app, tap the × next to your Gmail address under Synced Accounts to remove it, then add it again. (croissant.com lists your connected inboxes under Gmail in Your account, but you remove one in the app.)
No Gmail account?
Right now, Gmail Sync is the only way to import your past receipts — other email providers aren't supported yet. It's something we may add as the product evolves, so keep an eye out. In the meantime, any email works for your future purchases — shop with the Croissant browser extension installed (see Set up the Croissant extension) or pay with Croissant Pay at a partner's checkout, and those items are added to your Collection automatically.
Why an item might not appear
Most often, the item simply isn't eligible for a buyback — that's the likely reason, not a syncing glitch, so there's no need to keep waiting and refreshing (see "What qualifies?" just below). Eligibility isn't fixed once an item appears, either: resale value moves with the market, so an item can drop below our buyback minimum over time (see how buyback value works); and imported items reflect what a brand partner currently has on offer, so an item can age out of that window as the partner's offer changes.
Two less-common causes:
The import didn't finish — try it again from the start.
The app needs a refresh — close and reopen it, and make sure you're on the latest version. On croissant.com, reload the page.
The size on an imported item looks wrong
Imported items come from your receipt, so the brand and style match what you bought. The size can be out of date — if you exchanged the item for a different size after buying it, your Collection still shows the size on the original receipt. That's fine, and there's nothing to fix. Start the sale and send the piece you own; size isn't what we match on (see Item eligibility & sale limits).
What qualifies?
Not every imported item is eligible — items from unknown or unsupported brands won't get a resale value or a sell option. An item that doesn't qualify when your purchases sync may not be added to your Collection at all. An item that's in your Collection but isn't eligible for a buyback can't be sold. For what qualifies, see What items qualify for buybacks?. Unsure about a specific item? Email [email protected].
Ready to sell?
Once an item is in your Collection, you can sell it like any other. For the full walkthrough, see How to sell items with Croissant.
