Well, our total invite list is 126, including kids. So...how many things do I register for? Obviously things at lower & higher price points, but there are some in the family who are fairly well off that could buy 2 or 3 things, and others who may not buy anything... I was thinking of trying to get about 150 different things on the list, but then I've heard it's greedy to have a big registry. I just want people to have options, not look greedy. So is there a "rule of thumb" here?
