Every membership can have an optional product associated with it that allows the purchase of the membership through your online store. If no product is selected, then the membership must be associated with the account manually or through some other method.
The Product Category object that this Membership applies to, if set, then any of the product in this Product Category once purchased will save this Membership to the Account of the user who purchased it.
