You scan your Costco receipts. When an item you bought appears on sale at the same warehouse, BulkBack shows it as a potential price adjustment with the possible refund and how many days are left to claim.

Bring your receipt (or show it in the app) to the Customer Service desk at the same warehouse where you bought the item, within 30 days of purchase. The item must be on sale and in stock. Costco decides each claim, so the refund is not guaranteed.

Common reasons: the item is not on sale yet, the sale is at a different warehouse than where you bought it, the 30-day window has passed, or the item is not eligible (for example gold bars, gold coins and bullion). Sale information comes from Costco's savings books and from other members who choose to share, so it can be incomplete.

Plus unlocks automatic matching of your purchases to sale items and price-adjustment alerts. Receipt scanning, your receipt history, purchase insights, the shopping list and the searchable sale book are free.

Subscriptions are managed by Apple, not by us. On your iPhone open Settings, tap your name, then Subscriptions, and choose BulkBack Plus. You can cancel there at any time; your access continues until the end of the paid period.

Open BulkBack, go to the subscription screen (or Settings) and tap Restore Purchases. Sign in with the same Apple Account you used to subscribe.

Apple handles refunds for App Store purchases. Visit reportaproblem.apple.com and choose your purchase. We can't issue App Store refunds directly.

On your iPhone. If iCloud backup is on, your data is also saved in your own iCloud account so it can come back after a reinstall or a new phone. We can't see it. See the Privacy Policy.

Sharing is optional. If you turn it on, the price, item and warehouse for a purchase or a sale item you add can be used to help other members who also share. No name, email or account is attached. You can turn sharing off at any time in Settings.

Use the Report option on the item in the app, or email support@bulkback.com with the item and warehouse. We review reports and remove content that is wrong or inappropriate.

Your receipts live on your phone, so deleting the app removes the local copy, and you can delete the iCloud backup in iPhone Settings. To ask us to remove information you shared with other members, email privacy@bulkback.com.
