- Expiration date and sell by date
- UPC Code cut off if possible if not write it down
- Write down any other production numbers
- Find company website
Once you've got this info simply pull up the company's website. Click contact and report a bad food item. 99.9% they will mail you a coupon for another item (usually worth more than you spent, this time you can get the supersized box) or send you a check for the amount you spent.
Sometimes you luck out and get a package full of coupons!
Think twice before you just throw it away!
If you are highly motivated take your receipt back to the store and get a new item that day. My receipts are usually thrown away or lost after my grocery trip.
