AbleCommerce Shopping Cart Software

I cannot figure out how to do the following:

When a customer orders 60 or more of an item, I want to issue a coupon that gives them a discount of $1.81 per item on 60 or more. On 59, there is no discount.
There is no place on the coupon to set a minimum order amount. The quantity amount only gives a fixed discount for the minimum quantity. If they order, say, 65 items, they get the discount for 60 if I have entered 60 in the quantity.

How can I get around this?

Thank you

Why not use the volume discount feature instead?

I don't want to do that because I want to be able to make special prices for different customers.

Some of my customers do large volumes and therefore get better pricing.

Hello,

You can assign discounts to user groups so that not everyone gets the bigger discounts.

Thanks Mike.

The problem is that I can't find any information on user groups - what they are, how to set them up and how you can use them. The instructions for AbleCommerce are very limited, and as my last shopping cart was Storefront 5, all the bells and whistles now available have me a little overwhelmed.

I will search the forums and see what I can come up with.

Thank you for your ideas. I appreciate it very much.
