Is there a way to setup volume discount pricing without having to enter in a coupon code? I'm looking for the ability to structure pricing automatically in the cart to reflect the following examples:
 
 
order reaches $250 retail, 20% discount is applied
 
order reaches $500 retail, 25% discount is applied
 
order reaches $1000 retail, 30% discount is applied
 
order reaches $1500 retail, 35% discount is applied
 
order reaches $2000 retail, 40% discount is applied
 
 
And, if possible, it would be great if the dollar value of the discount were shown in the cart (ie. "Your discount is currently $82.54).
 
Thanks!

You mean this: www.viart.com/shopping_cart_system_prices.html ?

Yes, that's good, but can that be done at a Product Type level? Having to set these discounts on a product-by-product basis is not feasible.

We have wanted the same thing since we started using Viart over a year ago, but it does not exist on a per order basis, only per product. This has always seemed very silly to us, since most online retail businesses are selling a variety of products, and not large quantities of one single item.
 
The only way we have been able to do it is by creating various coupons and notifying customers about them with notes in the shopping cart. It's rather archaic, but the best we can do until Viart catches up with things.
