Personal Shopper Gifts

My boyfriend got a women in the secret santa drawing this year, of course I will be the shopper for her…?
$20.00 limit and she has thing on her list like body baths and perfume and a sweater. I said I think she wanted a women to get her. Being a man those things are a little personal. Would a gift certificate be fine even though it is not on her list?
Don’t buy something that isn’t on the list. A gift cert for a body/bath shop is best; and not at all personal.
