Hi
I'm using Amazon and aramex. Both. And amazon is great. But it's better you calculate the item price correctly. Like for example:
1-When purchasing the item on line there is state charge. (depending on which amazon u are using. Amazon uk, or amazon USA )
2-Also there is a charge on visa/ master ( for example 2 % )
3-Also check the weight, very important. It's 65 qr per kg.

After all this, SOMETIMES you find things in doha is same price.

But , there are things after all this, is cheaper to buy from AMAZON

Regards,
