3 Postcards In An Envelope #3

Simple Swap. You're going to put 3 blank store bought postcards in an envelope and mail them to your 1 (one) partner.

This is sender's choice but it's always polite to read your partner's likes and dislikes, just keep in mind your partner might not have your specific likes on hand. :)
NO ad/free cards unless your partner doesn't care.

That's pretty much it! Told ya it was simple ;)
