value itself is always going to be a subjective discussion on here. we all look at it differently. you just need to figure out what really matters to you.
as a real value person, i can find myself being too cheap sometimes. so when i allow myself to spend more, i am very researched and careful, and even then knowing that chemistry is everything.
for FS i love the Micro160 ladies, I've found so many great times there, real good connections, the best bjs, all of it. $160 all in for some of the best sex of my life. and it really hits my value.
but then it makes it harder to cough up 140-160 for an hour massage with HJ. which is what some of the young/pretty/good ladies are charging now. I probably miss some great experiences all around because i'm frugal. but guys who want to pay for the "best" are probably paying for average service more than often and not knowing it. It goes both ways.
What i have learned - when you find the value lady, see them often, spend more than you might spend on full price, because you'll multiply your experiences and you never know when they'll be gone.
But also, when you find someone really good, worry less about a couple extra greens and make it happen.
