"The day I dropped off my wedding invitations at the post office, there was another couple there with a box of at least a hundred invitations (that obviously had the RSVP cards) who had already put postage on each of the cards, only to find out that they hadn't put enough postage on," Powell said. "I almost felt guilty dropping off my slim invites and slipping out the side exit."
"The online RSVP was wildly successful because we created an experience," Powell recalled.
Skipping the store, asking for cash
But speaking of that registry -- this may be the biggest potential pitfall of them all, so tread lightly.
Sites like Honeyfund and gofundme allow guests to give cash to a couple to apply directly to a honeymoon or a home down payment, or however they care to use it. The lucky lovebirds can even select various donation designations -- $100 will buy them a meal in Paris, $700 will cover airfare, $50 will go toward a foot massage after they take in the sites. It's the gift of an experience or an opportunity.
The object-free approach might appeal to couples who have been living together for a while and already have all the toasters and place settings two people could use. But for relatives and friends who are used to picking out the butter dish or gravy boat from the couple's china pattern for every wedding they attend, this can seem like a letdown -- or even a shakedown for cash.
It might take a while for sites like Honeyfund and gofundme to make it into the etiquette books, so in this case, it might be easier to engage with a store registry.
