I could believe it.
Think about it - how many customers will actually take advantage - 1 out of 100? 1 out of 1,000?
Pretty good return on their cost. You just mentioned to 10,000 of your closest friends - you and us will all feel great about BB&B, and probably be more likely to shop there.
However, only a very few of us will return anything. So the cost of your pans has got to be less than the advertising they would have to spend to get as many people to feel good about their store.
Return them in good conscience - they made a shrewd business/advertising decision that is no doubt paying off for them. :)
