I'm trying to put together an order for Parallels Desktop for Mac, both an upgrade and two full versions. On the Parallels website I clicked on the version 8 Upgrade button, and it added to my (empty) cart at $49.99 as expected. But there's no "continue shopping" button so I have to click back to the Parallels.com main page again. So I can now navigate back to the store and (tried to) add the 2-license full version for $109.99. Wadda deal! However when I clicked to add it to the cart, then the upgrade was removed from the cart! I can't seem to get both the upgrade and the new version in the shopping cart at the same time. How can I get both items in the shopping cart at the same time? I have to submit this for our purchasing person to buy, and I don't want it to not work since I'll just get my request thrown back into my face. I really want the purchasing person to buy from Parallels directly, since CDW does not offer the 2-user license bundle so it's much more expensive from them.
