We just booked for March 2020 and I also was surprised at the check only method of payment. Does create some problems being in Canada and not having a US funds bank account, but solved it by getting a bank draft and sending it by registered mail requiring a signature. I didn't have any problems with trusting the owners of BSV but was concerned with my Canadian mail system interfacing with the USPS but it all worked out. SXM, here we come!!
