If you can find some local business that you know for a fact does not have an Aldrich. etc. account (call and ask about the status of "your" account, perhaps?), and misrepresent yourself as a representative of that company to the USPS, UPS, whoever... you could open an account and overnight orders so that they would arrive when the company is closed for a holiday or some other reason, so there'd be no funny P.O. box business, and you'd still get to pick up orders at the shop... a lot more elaborate, but you would be golden with the right information like that...
