BackTwist - 25$
If you buy multiple tricks from a smartphone or an ipad, it is possible that the paypal button seems inactive. As soon as you will add one product in your cart, the paypal internet page will open and if you add any extra product, the page will update automatically even if nothing happens on our website. You can complete your order by going to the paypal page once you are ready to pay. If this doesn't work, try to do it from a computer.
