Cheapest way to get a business address? -

I m based in California and want to start selling things online. However, in my current city, a business license is required, and only addresses zoned for business may be used to apply. So, that (and stuff in my lease) means that I cannot just use my apartment address.However, I m low on budget. What would be the cheapest way to get a business address? Is a virtual office the best solution? Or, can I even just get a UPS dropbox? I m in northern California.

I just use a P.O. box for my business address. it s cheap and it keeps my home address private. Works great for me.
