I want to send seven people a check. It will be a surprise. I want it to be as safe and secure as possible. I would like to send it FedEx, but don't want to pay $31 each for seven of these. The only way I'd use USPS is if it was Certified/RRR, but I'd prefer not to use USPS. I'm on the fence about requiring a signature. Any suggestions?
Edit: Should it be a cashier's check?
