I am looking for mailable kraft envelopes for save the date cards for my small wedding. I only need about 50 cards, and anywhere I look, office supply store or online, sell in packages of 250 or 500. I was wondering if anyone had any extras laying around from a prior purchase? I'm looking for size 7 coin envelopes or A2 invitation envelopes. Let me know if you have any you won't be using & how much you'd like for them.
