Product price doubled

I installed PayPal Express module, added the first product and everything seemed to be okay.
Except that when I do a test and add one product to the cart, the price is double the amount.

To be a little more clear... I priced the item at .75. When I add one product to the cart, the price the cart shows is $1.50 even though there is only one item in the cart.

A link to your site would help

Check your currency settings, and make sure that your chosen currency is the DEFAULT currency, and that its value is 1.000000000000 .

Thank you both. It is working now. Do not know exactly how I did it. I spent a long time going through to the whole process again three times until I got it right. I checked the currencies like you suggested and someone also suggested to check the price in attributes... Anyway, it is working now. Thank you.
