Blank Postal money orders or Silver.
Postal money orders only, not from a bank or other commercial provider. Leave them blank and use as cash. Will depend on the vendor.
Any clerk with a brain will pay the bill with their cash and pocket the silver. Bought a car once with it. A Dollar is not a dollar, saved big on registration fees and insurance by reporting the silver sale price Keep an eye on the exchange rate though.
