Just catching up.
The key thing here is the 'local' - folk still get stung by international postage that is currently going in one direction (up and up) and as the world sinks more into recession anything that generates sales should be looked at - I can understand there is a matter of trust over sales but I hope for international buyers this could be overcome.
I don't see why not. There would just need to be some extra work involved. Labels, packaging, correct branding. My only issues are branding. For example, my company B models are also sold by other companies. A lot of these models took a tremendous amount of time to sculpt or develop. But almost all references to the product refer to it being owned by those retail companies and not me or company B. This means additional sales are constantly being routed to those companies. Granted, the world of .stl files and such is completely different. But this is also pretty prevalent on sites like Etsy, where the same STL files re sold by different print shops.
Another idea, would be do also develop specific ranges of models for different regions. An intriguing partnership idea.
