If you buy multiple tricks from a smartphone or iPad, it is possible that the paypal button seems not active. Once you have one trick in your cart, the PayPal page is open and will be updated automatically as soon as you touch the "Add to Cart" Paypal button, even if nothing is happening on our page. This is due to Smartphones security towards pop-up pages. If you can’t finalize you order from you Smartphone or ipad, please try to do it from a computer.
