Society & Culture in the US

I am going to a find a spa where I can get a gift certificate to use as a birthday present. What do you give someone who has everything, and sometimes two or three of everything. I for one hate to keep wasting money on just things. Things that will end up on a shelf in the closet or in a drawer where once in a while someone will wonder why it is still there. This gift certificate is going to be for a facial, or a massage or a waxing. I haven’t decided yet. Even a manicure would be a nice present for a girlfriend. I will just hope I don’t cause offense by give a certificate to a Chicago facial hair removal place. I will have to think up a way to give this certificate so they person getting it does not think I am saying that it is something they need, instead of something they will enjoy. I guess I’d better let my girlfriend know that I know she likes to keep up her appearance, so I thought of a way for her to save the money she usually spends and maybe buy and outfit to go with the certificate.
