I have multiple vendors, and I need them to be able to enter orders for their customers, without paying through Catalook.  I tried making a price rule that made their products free to them if they were logged in.  This does not work because as they change the customer's name and address, it changes the vendor profile to that name and address.  Every order they place gets assigned to the most recent cusomer they enter.

I tried creating a large coupon that would cover the cost of any single order.  Except that if the amount in the cart is negative, it still wants payment info (unlike a cart with a 0 total).  I thought I could fix this with a price rule (if amount in cart is less than 0, make the cart amount 0) but you can't make a rule for cart total, only quantity (right?)

I need a coupon that will allow vendors to enter orders for various cutomers without being charged.  A 100% off coupon.

Is this the only way to accomplish this?  Is there a simpler solution I have not thought of?

I am using dnn 4.5.5 and catalook 5.3.9, but will upgrade if that will fix the problem.

Cart level percentage off coupons are supported since the v05.04.03. Please find all information in the release notes on the download page or in the manual.
