I'll admit, it's my own fault for not checking the size requirement for the $1.00 back rebate for Banza pasta (any variety, 8 oz only).
But why in the world is the 8 OZ ONLY rebate redeemable at Costco, where the name of the game is buying in bulk, and the spaghetti I purchased is 5, 8oz bags? Indeed, the only Banza product on the shelf at my Costco. One package of 8oz is a normal grocery store item.
This should not be listed in any bulk warehouse store where a reasonable user would assume that the offer would apply to a warehouse, big box-sized package.
