Hi Girls,I have found a design for invites that I really like and seem pretty reasonable in price. I'm trying to figure out my package (to also get a ballpark figure of how much these bad boys are gonna cost me) and the option is RSVP card with envelope or RSVP postcard. Regardless, either way they are the same price, but I'm trying to see which way are most of you doing your RSVP's? Postcard style or RSVP w/ envelopeTIA
