I'm looking for a gift in the $20-$30 range to give to my 2 FSILs when I ask them to be my bridesmaids. I was thinking about maybe a gift certificate to a nail salon or something like that. They both live out of state and we're visiting them this week so I'd prefer something I could buy in person rather than online. I probably should have done this earlier but the idea just sprung to my mind this morning. TIA for your suggestions!
