Private trades average a wide range of .90-1.05, .90-.95 being the low end of course with cryptocurrencies. 1.06-1.19 is the grey area between that of private trades and websites - its very rare that private trades will go above that 1.06 point nowadays, usually people with lots of vouches will abuse their vouches and charge above that 1.06 mark because they're "trusted," but in reality the average price is $1/m, for pp at least.
And then ofc there's websites as we both know that just scam the hell out of people.
