Sorry it took me so long to respond - I don't get here as often as I'd like these days.
Actually, I already had, about a month ago, and I got back an email last week (after a month?) saying they were aware of the problem - it's something to do with putting data in the custom field - and they were working on a solution. Meanwhile, I found a workaround by co-opting another field.
Umm, I'm having accuracy problems with urchin.js too. Thought I'd mentioned that. I don't see any zero revenue transactions, like with the new code, but the reports are different from one section of GA to the next.
For example, for the period from Jan 27 to Feb 26:
On the Ecommerce Overview page, it says 859 transactions, 340 products, $112,587.69
On the Transactions page, it says 858 transactions generated $112,587.69 (I assume this number is minus shipping since shipping is listed at $16,673.85)
On the Product Overview page, it tells me 340 products generated $93,758.43.
Somehow I lost a transaction between the Ecommerce Overview and the Transactions page, and I don't understand the dollar amounts at all - even if the $112k includes shipping, the $93K product number plus the $16k shipping don't add up to the $112k total.
Now, to *really* screw this up, the actual totals out of the actual store for that period of time are $103,108.77 for product and $17,896.29 for quoted shipping - and that was AFTER a handful of cancellations, which obviously GA wouldn't know about.
And this is all with urchin.js. And I have the similar situation across four separate Ecommerce sites, two of which are Zen Cart, one is OSCommerce, and one we wrote from scratch.
You can understand why I'm confused and disoriented, ork ork. We have sent this data off to support, more than a month ago, but after a couple of initial exchanges, no more communication in weeks.
(And I haven't checked any of this against AdWords data yet)
All that said, I came up with another idea that I would like to see in a future version, if you don't mind the suggestion. Have you considered something like an MCC for Google Analytics? I create and maintain a lot of accounts and profiles for my clients, and they're all linked in to my Google Analytics account. Over time I have developed a set of common filters that I need to be able to apply to all the accounts linked in to mine, but there's no easy way to do this. In an MCC type situation, I could create all my filters in MY account, and then apply them to all the accounts I'm linked in to for which I have administrator access.
Just a thought.
