FS: (2) Ben Garelick Jewlers $50 gift certificates

Ben is leaving the company to his kids. So they’re using that to have big “sales.”
As far as I know, they’re sticking around. I hope so, I’ve been building an Add-a-Pearl necklace (no jokes, please) for my niece, and they’re the only source in town.

Maybe I’ll pick these certificates up. Are there any strings, like “not valid on sale priced items,” or any crap like that? Are they the same as an in-store credit?
