Frequently Asked Questions 1- Anything else I need to know? Everything from the FAQ at our main BST applies to this one. The only difference is that unlike with our main BST, you MUST use your Paypal email address to order. Each transaction will be verified to make sure there are no repeat orders or attempts to circumvent our ordering system, and any repeat orders will be immediately refunded upon detection. Don't forget to include your contact email in the "Order Details" field if your Paypal email address is not your main one.
