I live in an apartment and run a high volume Ebay business. About 2-3 times a week I get large shipments of items from suppliers, and maybe 5-6 returned items on top of that. At first the apartment office did not seem to mind but I get the sense recently they are getting fed up with the large shipments and boxes they need to keep in the office until I pick them up. Are there any mail solutions for this kind of business? I know I can use UPS store but I think they will also bitch at me if I get a tiny mailbox that gets large box shipments almost daily.The business is growing and I need a scalable mailbox solution but there don't seem to be any.
