Hi! If you can, please send me a pm with your email address. What the problem uasually is, is that when paid with PayPal they often don't let your payment go through because they have found your PayPal account to be suspicious. You can easily find this out when you look into the transaction. Unfortunately, Cubebrush can't deliver a product when it's not being paid for.
When PayPal has marked your account as suspicious, it'll take a while before they clear your payment. As soon as they do, the transaction will complete and you'll automatically get sent your products.
