It's the US companies that are blocking none North American IPs. There may be many reasons for this. Firstly, they do not ship internationally and IMO would think mainly for logistical reasons (Shipping Internationally Taxes, Brokerage fees, risk factors etc etc list goes on and on. So now they block you to save money and not bog down their servers, bandwidth costs money!) Its not the local dealer, they don't even make effort to stock their shelves.
Think about this: (A local dealer, say a Honda in Trinidad, cannot cannot block IPs from Trinidad directed to some other company in the US or the world for that matter) Only your ISP, The Government, and the Company via their web host and or website backend can.
Both
WWW.SLHONDAPARTS.COM and now
