Print-On-Demand postcards in the US?

Anyone know of a company that prints & ships individual postcards on demand in the US? Especially higher quality fine art postcards.

Plenty of companies sell postcards and Printify will ship individual ones in envelopes (with $4+ shipping...) but I haven't found any that will actually ship them as postcards for a reasonable price. Prodigi will print & ship them in the UK for $1.50 total each, but not to the US.

Please don't tell me to ship them myself, there's no mail pickup where I live and I want to minimize wasted time.

Thanks!
