Thanks for the support. My LBS has a great return policy. It is the largest bike shop in the area and they do tons of business. The salesperson knew that it was a surprise for my husband as I had mentioned it several times. The bike was never touched/ridden so they can still sell it as brand new. I'm just embarrassed because I made such a big deal about buying it and picking it up, only to have it returned a week later. Definitely will buy tother stuff from them but I still feel awkward.

Tulip - you are quite right - I really should have known better than to assume that my DH would be interested in something just because I am interested in it.
Oh well. Lesson learned. Thanks all!
