Thread: Maximum Quantity

Is there a way to limit the quantity a user can purchase on specific items.
We need to set a maximum quantity per year and a lifetime quantity.
For example, a user will be limited to a quantity of 20 pieces on a specific item per year and a lifetime limit of 100 pieces.

There's nothing like that built in, but it wouldn't be too difficult to add. You could add a check on the shoppingcart.aspx page to look through the customer's previous orders and adjust item quantities down and shouldn't even need source.
