After having put some days of work into creating my friends book site (iktami.com), I decided to keep it simple and implement Paypal’s “Add to cart” buttons.
Wrong choice.

You see, I was under the impression that Paypal’s shopping cart would be able to handle shipping cost based on weight. But no, it isn’t. Well, only if you’re a merchant residing in the US.

What? I thought computers and the internet would help bring an end to discrimination and suffering.

What could be the reason for this? I am sure it’s not a technical problem, because that little and simple piece of code is agnostic of location. And it isn’t money, because they would probably make even more if they didn’t piss off merchants outside the US.
Maybe they just don’t care anymore, having all that money, and getting (re)tired of it all.
Or, could it be some political hidden agenda? These things pop up everywhere these days.
I am probably missing something here.
