Membership allocations are typically shipped on a defined frequency or interval.
For example, your Founder's Club membership level might ship every three months, or four times a year. Then, your Winemaker's Choice level could ship every six months, or twice a year.
To update the shipping frequency, simply select the proper option from the drop down. Changing this will change the text on your website. It doesn't effect memberships or processing in any other way. Frequency is simply one part of your membership level description.
Bloom provide two shipping options for membership levels. Free shipping, which is often used instead of a discount, or you can elect to use your store's shipping rates. Using your Shopify store shipping rules means that club orders will have the same shipping rates as orders created from the website.
Simply select the option using the drop down.
