Oh no, I meant Retail! ^-^ The Retail method, where you put random items like unassessed fossils, flowers, junk items, etc. up for sale in Retail for max price (which I believe is 1mil bells per item) and I purchase them all, then drop them outside later if you want them back. You'd have to keep putting items up though since there's a limit of 8 items, and I don't think you get the money in your account until the next day, so picking up in my town may be a better solution. Plus I can only carry about 2mil at a time. Let me just lay the money down, it'll probably be about 5 minutes.
