What kind of UPS collect experience is out there?

Some time ago I sold a pair of speakers to a fellow in SF, CA and he wanted to do UPS collect. It took UPS 40 days to get the money from CA to Wash. State. Recently, I sold an amp to a fellow in NY and he wanted to do UPS collect. This time it took them 27 days to get payment from NY to me in Washington. Any similar experiences?
