Be careful on where you decide to register. For our wedding I registered at Target and bed bath beyond. Returning items to bbb was a breeze, Target on the other hand was not. I left the store twice because I was about to freak out at their idiot policies. I'm sure we will be stressed enough without having to deal with a painful return process. Just an fyi.
Re: Beware of Target
That's strange, because in my experience, I feel like Target has the most liberal return policy I've ever experienced. I've often returned gifts (non registry) without a receipt (the gifter would tell me they purchased the product at Target) with no problem (so long as I accept store credit, but I shop there all the time anyway). Even when I returned the gift months later. Must be dependent on the particular store??
