Return Baby Einstein DVDs with no receipt

Perhaps a candidate for Hot Deals instead of Finance, however I thought there might be a good opportunity here:

"the current offer, allowing parents to exchange their video for a different title, receive a discount coupon, or get $15.99 each for up to four returned DVDs, requires no receipt, and extends until next March 10." DVDs had to of been purchased after 2004.

A few months ago, we received three as gifts, coming out of a buy one get one free deal... with at least two people in the family with credit cards, if you can find a similar deal it could be a relatively easy $60.

thanks but this has been already posted yesterday
