Amazon has diffrent pricing for affiliates. I recently created a astore where amazon has almost 25% extra pricing for all the prooducts. If suppose a product price is $100 on amazon.com , its showing $125 on my astore. If is right?
Please check the pricing for any product on your astore and then go to amazon.com and check again... you may find the diffrence... For few products pricing is same too...but not for popular one...
