Buyer-selected packs

Hi everyone,

I don't know how technically feasible this is; but I think it would be a good idea if buyers could get automatic discounts when buying a certain number of products from a single buyer. The discounts could be fixed per amount of models. For instance, if a buyer decides to buy 3 of my models at the same time, he could get 20% off the total price. If he wants to buy 5, he could get 25%, and so on. That way he could buy the models he is interested in instead of having to stick to seller-preset packs of products, and still get a discount for bulk purchase.

I'm terrible at explaining things but I hope you guys can understand what I mean.
