I get this quite often, I have one that has been waiting for 8 days now. I personnally will wait 30 days, never had to wait that long, but I am generous I guess, and really not in much hurry, I may have to wait a little over a month to relist the item, if it came to that. Some people are just slow, but even more of the case, is the people who don't really get on the computer that often. I have a friend that won a ebay item, and forgot to check for several days, he may check his email every couple of weeks. I think personnally one should wait at least 7 days, then it is up to you how long to wait.
