Pussy in volume? Isn't there a BBW search qualifier just for that?
I will admit I've seen some providers who advertise different rates on here, on BP, and especially some who also have Yahoo groups. If you're a hobbiest who has done the due diligence to look over a girls Yahoo and BP postings on top of here, and/or P411 I would think she should honor the lower rate if you mention it.
Now on the other hand I have also seen providers who make the move from BP to here and suddenly think the same service, same incall location, same everything is worth more because they've "upgraded". This is one of the treacherous first signs of the dreaded.... GPS.
This doesn't only happen in this "world" either. I know Baker Brothers Plumbing charges different rates if you do or don't identify yourself as a P1 (listener of a specific local radio station) as i've had work done by them twice and the time I forgot to mention it the rate was higher.
