Discount Store Product

[SULINK]

The current product discount system in the shop works like this:
The product costs 5.00. If the customer takes more than 10 for example the product equal number 11 would leave for 4.00. So getting 10 products for 5.00 and 1 for 4.00.

My proposal is that the discount be the same as several online stores thus:
The product costs 5.00. If the customer takes more than 10 products, each of them will cost 4.00. thus giving a discount to all products, not just 1 product as it currently is.
