Despite advances in technology that make it possible to find the nearest bathroom with your smartphone, emailed wedding invitations are still frowned upon. That doesn't mean, as Kerestic notes, couples shouldn't be emailing save-the-dates and working the phones to round up friends and relatives -- and getting ready to fork over a bundle for the pulpier product a few weeks later. "Place an order for the things that, by nature, take four weeks to deliver and accept that you'll have to pay more for them," Naylor says. "Invitations are pretty rare to get in less than two weeks." There are some ways to soften the blow, however. Naylor recommends do-it-yourself invitations from such sites as Zazzle and MountainCow -- which features software for designing invitations, save-the-dates, meal cards and scrapbooks as well as custom stationery -- and not just stopping at the first site with something available. "You have to be very flexible and devote a lot of time to doing the checking around," Naylor says. "Big money mistakes are made when you settle just because you only have that month to plan."
