Amazon Prime Canada?

Does the Amazon Prime perks only work with and not I can’t seem to link my Canadian Amazon Prime account with this site.

Did you log in with through Amazon?

I’m guessing only US Amazon Prime.

What perk were you looking for? We don’t usually ship regular deals outside the US, and we can’t do express shipping internationally on the shirts…

The only perk I know of is the free express shipping, but it’s more me wondering if I’m missing out on the deal 'cause I didn’t see something, or if it’s 'cause I’m in Canada.
