I'm sure this has probably been covered before but I can't find it in the topic searches.
Anyway, I'm very pleased with joomshopping it fits the bill for me just about perfectly!
The only issue I have is a lack of frontend admin. I'd love to be able to have frontend access to administer the shop, or to be able to hand over responsibility for that to someone else without having to give them backend login.
