Contacting a (Potential) Buyer

Hey all. Someone contacted me to buy 2 cels from me, and I don't have that person's e-mail address anymore. Does Rubberslug happen to keep a master copy of requests that go through the shop? Thanks!

Depends. If they have an account, I can find their e-mail address that they verified their account under. (This is why an account and account verification is required to do a transaction in the shop.)
