Thanks for these, its looking like a good solution for us, few more queries!
1.Do you know how long the Google Merchant Centre will take?
2. For the 'registration' option, can it be combined with the others, i.e. giving the customer the choice to register or not?
3. As standard Joomla reg, will it work OK with Extended Reg?
4. Can you use the commenting systems to act as a customer review, or is there a better way?
5. Is there a like/ tweet product option somewhere?
Lastly, I see you have been removed form the JED?
Thanks
Daniel
