By default in OpenCart "discount" option is almost hidden and presented to buyers or admins not very well, but this is great feature that allows you as a store owner to sell more items at once:)

This mod will help you to achieve it. It will change the layout and look of your products page to make it more visual appealing to buyers , that buying more than 1 item is a "WIN WIN " situation for both sides.
Buyers will see all discounted prices in a more professional and eye catching layout. And for admins it means more sells:)

You as admin can from now on hide some discounted prices in admin products section, so in order for user to see the discounted prices on xx quantity users will be "forced" to register and login.

This is a " WIN WIN SITUATION" for both. As admin you will sell more items and as a buyer he will get lower prices. (at least these discounted prices will be at his view in a professionally  presented format view)

This mechanism is used on a very good known drop-shipping company http://chinavasion.com.

and believe it or not, i do also get "hooked up" by these discounted prices there and combined my purchases with my friends and family in order to get the items we want for lower price:)

So do not waste anymore time get the mod and set your discounts and hook up your clients in a new way:)

PS: that is not all, once user will change the quantity in products page the price will be auto calculated based on the discount price ranges.
