I can echo what Jerboa has said as I have fallen prey to this myself in the past. One example, there was a very pretty red haired girl called Verity who used to be listed through Hamiltons / Bijoux or Allure for £300 / £350 for quite some time. She looked very tempting even at these crazy prices, but luckily I never booked her through them. Last year I found her on AW for £250 and took the opportunity (still expensive) and no shortage of services provided there either. I was lucky here, but in other previous cases I have only later realized that the girl I have seen has been listed cheaper elsewhere on another site / AW.
All you have to do is read the thread "slow at the minute or just me" on saafe, which has been running almost daily since 2008, to get a sense of just how bad business is for these ladies.
Some other live examples I have come across recently (not visited any of them though):
1.
External Link/Members Only listed here at £200 p/h, whereas she is listed here at £300
External Link/Members Only. (I have even messaged this lady to see what services she is happy to provide and it is no different to what is stated in barracuda).
2.
External Link/Members Only listed here at £350 p/h, whereas she is though listed here at £160
External Link/Members Only3.
External Link/Members Only listed here at £500 p/h, whereas she is listed here at £200
External Link/Members Only4
External Link/Members Only listed here at £600 p/h, whereas she resembles this profile at £150
External Link/Members OnlyIf they are doing so well charging a higher rate, why do they have another profile charging cheaper rates?
The only high end type agencies I would recommend are Maxes, Bijoux, Hamiltons and Allure.
