Multiple addresses for shop bots?

OK lads I'm a bit stuck, I'm writing a fashion buying bot for limited releases but how on earth do I get multiple addresses.

yes i could ask friends and family but I'd be looking at 20 addresses tops where as ideally im looking at 250 - 500 addresses.

Payment, proxies, email addresses and the actual bot I've written are all flawless but I'm left with this stumbling block.
