what version of ubercart and userpoints are you using?

I would like to allow discounts with the module in the future. At present I didn't have the time to build something like that into the module. I am just not sure how to go about that yet. I am open to suggestions on how to do that, my big problem is that you would need to execute two payments to do that and have it be fully paid for, if i could solve that i'd be ok...
