Auto billing; when and how to use it.
Your CSA subscription(s) default SKU is a recurring/single delivery payment. If you intend to bill in this manner, leave this SKU alone. The dollar value amount is taken from the share set up sizes/prices, so there will be one default per share size. If you wish to collect payment for the CSA boxes in larger, but still recurring, credit quantities edit the Recurring Billing frequency in your product settings. The member will be billed as follows: price of one box x recurring billing frequency.
