I'm a member of an organization with several hundred members scattered around North America. We would like to register with an online merchandiser so that our members can order ball caps, T-shirts, etc with the name and logo of our organization on them. The merchandiser would then ship the purchase directly to the buyer and pay us a percentage of sales. This would all be linked through our organization's website. I know there are lots of online "swag" stores that do this, but I'm looking for recommendations for/against. BTW our organization is based in Canada although about half our members are in the USA. Thanks!
