We have recently upgraded a client's site to Joomla 2.5.6, Virtuemart 2.0.10. The site is http://thestainstore.net/
The problem we are having appeared when we added the istraxx_ups extension.
The problem is when we go to checkout, the product prices change. This happens at the point where a customer provides their shipping information. For example, the product HCorp Chemical Stain, found under Acid Stains (http://thestainstore.net/products/acid-stain/hcorp-chemical-stain-detail.html) goes from $58.00 to $58.05 when shipping info is added (it does not matter if the person logs in first or not--they can be checking out as a guest or as a registered user and it still happens.)
Any idea what is going on?
This is a live site, so would really love a quick solution.
Thanks!
Additional info:
This problem does not appear when using Chrome. Having problems with Firefox (15.0.1) and Safari (5.1.7) on a Mac. Have not tested in Explorer yet.
