You have to provide a bank account (not paypal) or get a check. You get paid 60 days after the month where you hit the minimum sales (different minimums for different payment options).
So, say you hit the minimum this month in May. August 1st or so, you should see some money fly into your account or a check land in your mailbox for May. Then September, you'll get a check for June, etc. as long as you meet the minimum. If you don't, you skip that month and catch up again when the amount hits the minimum.
