It is unclear currently how to use coupons. suggestion: on the "billing" tab, provide a link to either use a coupon, or give you directions to one.
That is correct the promos are for credit card signups under the billing page where you enter in the credit card information.
turns out that if you register your account using paypal, there *is* no way to use coupons. So maybe...this would better be stated as "a way to use coupons with paypal"
how do you use a coupon anyway?
