I use Payal to ship but I'm looking for other options. I'm irritated this is the 3rd time in the past few months I can't ship for a day or more because it's unavailable. Not sure if it's a paypal or USPS problem.

All shipping companies (including USPS) have COD options... have you tried those?

You can open an account with USPS and use priority shipping. They will pickup from your home.
