I just waisted a month of time trying to create a new site with Drupal Commerce and almost lost my client (who I do numerous projects for) in the interum. I finally worked up to having it nearly complete only to find out that Shipping was not given any serious consideration and that as of just a few days ago there was NO workable/stable solution to shipping. WITHOUT SHIPPING an ecommerce site is useless... you have to charge a customer for shipping, no? If you wanted only FLAT RATE there was a pretty bare bones implementation of that that barely worked until there was an update of Drupal Commerce to beta 4... then all hell broke lose on what minimum functionally existed in the so-called "shipping api"...

So I've been workint 16 hour days for the past few days in a frantic attempt to set up the site from scratch using UberCart and I have to say, I am happy I did... Drupal Commerce, while good in theory and on paper, is FAR FROM ready to be used now... and with the last beta 4 release (a decidely uncoordinated effort requiring all updated DEV versions of views, rules, etc.. and a special patch applied to Rules to get it to even work)... and the onslaught of bugs introduced because of htis rushed-out-the-door update (as much as I respect and admire the developers of Drupal Commerce, it was a far bigger blunder than anything Microsoft has done in thier long tarnished history of buggy releases and patches)...

Most of the 'in development' and 'not-quite-ready-for-prime-time' add-on modules for Drupal Commerce ... come standard in UberCart out of the box... and while I agree Ubercart has a lot of lacking features (ie; attributes on products suck! to create a 'country' drop down as an option/attribute, you need to manually create upwards of 260 or whatever countries as Options"... time consuming and unneccessary but what can I do?... but even with the lack-luster parts of UberCart, at least it IS ABLE TO WORK NOW as a eCommerce Solution... Drupal Commerce is not... and mostly for the entire oversight/lack of a decent Shipping Module and Shipping Quotes...If you can get by on flat-rate (which only a limited amount of sites I can think of coulld)... then maybe Drupal Commerce is worth the dive-in now... and if you don't mind not having a lot of the 'nice' features already in ubercart that require add-on modules in commerce (some started, some have not)... then again maybe Drupal Commerce is worth a look..

HOWEVER!!!!! If you need a WORKING eCommerce solution that is stable (or at least even mostly stable) within a month or two, then UberCart seems the only realistic way to go.

Maybe in half a year I'l revisit Drupal Commerce and see how time consuming it will be to export from UberCart to Commmerce and try to upgrade then.. but for now... its been a month of mistakes, waisted time, lost hair, stress, etc.... trying to get a workable solution out of Drupal Commerce... They should be more clear in their promoting of it that it is NO WHERE READY for prime time... that they should be looking ONLY for beta testers who are not trying to do something 'real world' now with it. I bought into the whole hype of "Its the future of Commerce on Drupal and ready now" and wish I had been wiser when I decided to give it a shot.. Time is money and time waisted time is money lost... figure that out over a month of LONG days 7 days a week... I've been kicking msyelf since day one of installing Commerce.
