I've got two showers coming up in different cities, one at the end of the month and one in the first week of August. The wedding is August 21st. We've requested on our registry that if people would like to purchase a gift, they do it so that we can pick it up from the store in the city we live in, as opposed to the cities where the showers or wedding are taking place. My question is whether I am still required to send the thank-you cards within three weeks after the showers take place, even though I won't actually have received most of the gifts until I am back here at the beginning of September. I'd appreciate some advice on what to do, here.
