Golden State Mint has a sale on their Standing Liberty one ounce round at 69 cents over spot, but they have a $500 minimum order which amounts to about 30 ounces and it comes with free shipping.

This sale ends 5/31/2016

For those that like GSM products, this is a fairly low premium, especially coming directly from the mint. I can't speak for the quality of this round as I've never ordered one ounce rounds from them.
