There is one glitch, though. On a test account I have a gift certificate. Once the order-steps arrive at the final "success" page, the order table conflicts with the gift certificate box. Here is a screen grap image of it in Firefox:
In IE it is even a bit more extreme as the order steps table collapses onto itself in a very unattractive way. (I do not, however, have ScreenGrab in IE to show you those dramatic images)
Maybe this is addressed in the latest version, as I'm running 1.1, but I thought you'd want to know.
