Commodore always sold far better in Europe than in the US, even for most of the 8-bit days, and they managed to totally burn their dealer network in the US in the early 80's and never recovered (the final straw was when Tramiel lowered the price of the C64 drastically overnight without warning dealers or offering refunds, leaving dealers with large stocks of C64's bought at the old wholesale price that they'd be unable to sell with much if any margin).
As a result Amiga sales in the US were small and driven by things like the Video Toaster on the high end where people for some time bought Amigas for the Video Toaster rather than the other way around, while sales in Europe were far higher volume and more focused on the low end models that there just wasn't a decent dealer network to handle in the US.
