After checkout, at order review, if somebody for some reason clicks 'Back', the lines containing tax are duplicated. It happens on ubercart 2.0-beta5, another user (Bentley) also confirmed the bug.

Re: tax recalculation at order review
Have the exact same issue. Rather disappointed that the reported issue doesn't include a patch or rev number.

Is there anywhere this can be flagged? IMO this should be a show-stopper for 2.0-beta5.
Re: found it...
That commit message indicates this was fixed on March 11. Are you using the latest dev release? If not, can you test it to make sure it solves your problem?
Re: Re: found it...
Same issue here - we have 3 different sites doing this on the latest releases.
It's also an issue with the order history - if you edit and submit an existing order with tax, it adds another tax line item which then gets added to the order total.
Same Issue
Drupal 6.10 with ubercart 6.x-2.0-beta5. Noticed when entering wrong credit card and having to hit back. After clicking review order again. tax was being applied multiple times. Kinda of a show stopper
About to go live with a store in the next week or 2.
Re: Re: found it...
Ryan, I've tested it briefly with the fix indicated in the march 11 check-in. Seems to work OK... But I'm more concerned that this issue hasn't been flagged as a showstopper for 2.x-beta5.
Sorry Still A Noob
Sorry I'm still a noob to drupal. When you say "fix indicated in the march 11 check-in" what are you referring to? The latest release was on 2009-Mar-02. Are you talking about some type of patch I'm not aware of? Thanks in advance.
edit: after doing some research I found this patch. Is this the one you are talking about? http://drupal.org/node/377064#comment-1330056
Re: Sorry Still A Noob
The dev version had the fix in it because it was updated on Apr 3. However, I've just released Ubercart 6.x-2.0-beta6, so you can upgrade to that and have this fix as well as several others.

If this question still needs to be answered, it's because it wasn't a showstopper any more. It was already fixed. 
Now it's a moot issue, so it won't come up any more in the forums.
