Traditionally, members do not have a choice as to what items will be
offered as part of each share from week to week. However, many CSAs
have begun employing a variety of alternative delivery systems. For
example, some CSAs now use a “mix-and-match” or a “market-style”
approach. These CSA programs cater to personal preferences among
individual members. Rather than giving all members the same allotment,
each member is allowed to pick what they like from the farmer’s weekly
offerings. Items that are in limited supply, such as strawberries, may be
restricted to one portion per member (31). Other CSAs offer the option of a
full share or a smaller half-share in which members either couple up with
another shareholder or they are given half the normal allotment.
Additionally, some CSAs offer basic or gourmet options, which contain
different varieties of produce (28). Finally, some offer a bulk or “canning”
share that contains a large quantity of a particular item
