I still see regular providers occasionally but here are the reasons I go to amps.
#1- availability. “Sperm of the moment”. No screening, no appointments. Walk in pay fee, get what you came for -leave.
#2- service. They will do things most providers won’t. ie: TUMA
#3- value. No GPS. From the over-hyped to the brand new, the fee is pretty standard.
What I don’t like:
#1- communication can be tough
#2- usually not as attractive as all the hype suggests
#3- a lot of them are smokers so the DFK is a bit disappointing.
