Anyway, my mum insisted that I send out Save The Dates for our October wedding because we have a ton of out-of-town guests. So after pricing different options and having my fiance design us something totally awesome, the best/cheapest way to do them is to print them as 4x6s from KodakGallery (I'll be ordering a few test pics first to make sure everything's good before committing to the big order), and send them in little envelopes.
That's the part I need help with- the envelopes. Where's the cheapest place to get envelopes? Places/websites to avoid would also be extremely helpful. Color doesn't matter since it's just the save the dates, so I don't mind if they're boring white or off-white.
