I live in BC and own an online wholesale craft retail business and am in partnership with another person. I've noticed that a lot of my demographic has been from the United States. Now I've never looked at selling to the United States before because I know a lot of companies don't do it but I wondered why? Is it worth selling products to the United States from Canada? Is it not? And what do I need to sell to the united States ( for instance I had to register for a PST number in every province I sold to across Canada), any info helps, thanks!
