Here's the scenario. On my site at http://www.justmanuals.com most of my prices are $10.79 . I made a discount coupon for $10.79 to be used one time only and it works 1 time only. BUT.........some of my customer's have found that if you add 3 or 4 or more products to the shopping cart, then they get 50% off the entire order instead of just 1 product which is my intent.
How can I fix this?
I'm also looking for someone to do some customization on my site.

TIA.
