ideas for gift for wedding you're not invited to?

FH and I just moved within the last couple of weeks to a condo. The couple next door also just moved in and is also engaged. We don't know them really well, but in the conversations we've had with them seem to hit it off and she is super nice (was a wedding planner and already offered to help me plan stuff!). Their wedding is in a few weeks. Clearly we are not invited, but I'd like to get them a card and a small gift. I don't want to do gift cards or anything generic like that. Any ideas for something inexpensive but unique? Thanks!

Maybe a gift certificate to a home store, like BB&B? I think they would appreciate something like that. It's very thoughtful of you to want to get them a gift!

do you know their last name so you can see if they are registered anywhere?? I think that is what i would like most... something from my registry!!

eta: spelling!
