I just remembered that the points on my credit card, which are redeemable for a variety of rewards, can be used for gift cards to Bed Bath and Beyond! I have some points accrued and now I'm definitely planning to cash them in for gift cards to help purchase any favorite items that are still left on our registry after the wedding. Just wanted to pass this along in case it's useful for anyone else!
Whoever said it was supposed to be happily ever after is a big fat liar.
