Hi! I'm from expresscoin. We currently offer cash deposit, check, money order, bank wire and (by request) PayPal as methods of payment.
We're a US based company with a headquarters in Santa Monica, California (we love visitors!) and are registered with FINCEN as AML / KYC compliant.

I would be happy to answer any questions you have, or help you place an order with us. Let me know!

All the best,
Jeff
