We have been married for a month now, and the stores that we registered for have the standard 90 day window to take advantage of an extra 10% off for the items not purchased. I started to sort out the items that weren't purchased for us, and hoped to finish up our registry in the coming weeks, when I realized that there were a bunch of people that didn't get us a present. I know they aren't required, but I did find it a bit surprising that so many people that attended our wedding had not gotten us gifts. Ultimately I don't really care, but my question is how long is an appropriate amount of time to wait before purchasing most of the remaining items yourselves? Thanks!
