Driven by the need I propose an idea addon for wp e-commerce:
I need a plugin similar to minimum order quantity but allowed purchases for multiples of x variations / products on my next site wp e-commerce.
Product A> 100 x 200 mm. > Box 10 pcs. = Multiples of 10 are only allowed to be Purchased
Product A> 200 x 200 mm. > Box 15 pcs. = Multiples of 15 are only allowed to be Purchased
I think such a plugin can be useful to many traders
