Adding a minimum quantity on a cart item

I would like a product page to have a minimum "add to cart" quantity. Right now I have a default quantity of 4 but when you add it to the cart you can update it and make it "1" if you choose. The quantity should be a minimum of 4 with the option to order more if they choose. How do I accomplish this? Thanks!

will this minimum quantity apply to this one item or others?

you could set a minimum quantity on a product by product basis by adding a new column to the cart and naming it minimumQuantity

in the add to cart button behavior set this column to the minimum you would like customers to purchase for that item, themn create a new calculation as:

abs([Quantity] < [minimumQuantity])?[Quantity] = [minimumQuantity]:""

that will force the Quantity to be the minimum set for that product if they try to set it below the minimum allowed.

Hi Jason, thank you for your reply. This will be added to all products on a page or in this case there are two repeat regions on this particular page, so the minimum would be in place on all items of each repeat region.

The minimumQuantity cart rule suggestion from my previous reply will work for this.

Hi, Ray ... does this explanation of minimum quantity have an option to be turned on and off, depending on whether the shopper is a wholesaler or not? I would certainly like the ability to implement minimum order quantities for wholesale shoppers and they would vary from product to product - do you have a suggestion for this work flow? Thanks for all your help, as always!

Yes, you could add an IF statement so that it is turned on or off based on a session variable value.
