demonic makes some very good points. I am on the locked down thread, having been a member several times in 4 years or so of SA. I would add that the "expected amount" that girls on SA seem to want has really gone up in the last year or so. You can spend hours/days/weeks chasing to no avail, because these girls see themselves differently in the majority of cases, but there genuinely is gems out there. I currently see a girl weekly for £200 per month. She is 23 and simply stunning and ticks every box. I am more than double her age and my issue, which is more typical of SA, is that she wants me to leave my wife and move in with her. That type of connection is far easier on the site.
I would add though that via SA I have had bad experiences as well, wasted journeys, wasted lunch meets etc. But this is my 3rd girl that is below the price of AW and its great fun. I have yet to encounter a freebie, many others seem to have.
Oh and back to the pricing, I spoke to a girl 6 months ago. I had spoken with her a year previously and we nearly met, back then she was happy with £100 per meet. This time around, she wouldn't budge below £500 per month.
