No, at The Food Assembly, Members buy exactly the products they without having a minimum amount required. Nevertheless, each Producers set their minimum amount of orders they need to have in order to come and deliver.
In other words, the minimum amount is set on the Assembly itself and not on the individual Member. This is why you might have some products which will not be delivered, because the concerned Producer or Farmer did not meet his or her minimum amount of orders. Nevertheless, if this happens you will be notified through your order confirmation email a day before the Collection.
