An invitation, like a bodyguard, protects parties from crashers and is more likely to be obeyed if it weighs more than three hundred pounds. Send a potent party pronouncement with today's Groupon: for $25, you get $50 worth of personalized products, invitations, and more at HollyDays, an online boutique. Domestic orders ship for a flat rate of $5.
Voted by Nickelodeon's ParentsConnect as crafters of the Best Personalized Gifts, the personalized paper-product purveyors at HollyDays offer a dazzling array of uniquely crafted stationery, invitations, and stickers. Graciously follow up with guests after a baby shower with a dozen elegant thank-you cards, printed on heavy card stock ($10), or demonstrate a congenital unwillingness to be rude by sending 12 to a single gift giver. Accelerate the letter-sending process with a set of 200 spunky address stickers ($45+), or pester a phalanx of friends for RSVPs with a sophisticated and intricate wedding invitation ($1.70 each for 25–49).
