I've changed pay buttons from the "old style" one to new smart buttons. But I'm wondering.. what will happen if somebody will change the attribute "price" on the client site, using browser tool "investigate page". Actually I've checked it, and you can edit it and then select "pay with paypal" button, and...!? You are signed in and you can buy things with the changed/edited price! There is no double check on the paypal site.. So you can buy everything in the price you want! Or.. Am I wrong?
