I've create a Drupal/Ubercart website where users can pay for goods using Userpoints.

For some reason the first checkout screen shows a much higher Userpoints budget requirement than the order total.

I just ran a sample order and here's what it showed:

$469.66 - Order total
1723 - budget required (incorrect total, should be 470)
8068 - budget available (correct)

This only occurs once UPS charges are added in to the order total, otherwise it works fine. And when you click "review order" to go to the next screen it shows the correct budget required, and then when you process the order the correct number of userpoints are subtracted from the user's total budget available.

I think the error may have something to do with the UPS shipping quote. But that's just a guess.

Modules being used:

ubercart
uc_ajax_cart
uc_coupon
uc_option_image
uc_out_of_stock
uc_store_credit
Store Credit: User Points
Userpoints

I need a Drupal Pro to fix this issue. ASAP. 

If you end up being a real Drupal Pro and we work well together, I'll have a lot more work for you going forward once this project is complete.
