We do have a feature that notifies a buyer if they are trying to submit an order that does not meet your minimum.
If the buyer tries to submit an order, either a first time or re-order, and the total dollar amount is less than the minimum stated in the seller's policies, the buyer will receive a pop-up warning.
We do state that the vendor may or may not accept the order if it is sent as is.
The buyer can choose to add more products to the order, or submit it anyway.
The idea here is that we do not want to prevent orders from going through entirely since it is up to the seller to decide if they want to be flexible.
