To receive more bookings! Some feel if they have 2 or 3 ads with 2 or 3 different pics and numbers as 2 or 3 different providers then they have more of a chance of making more money.

I posted about on the review board after I got a nasty text from a provider who claimed I called 12 times when I thought I was calling different providers. At the suggestion of a reputable provider, I've gone ahead and gotten pre-screened so I can avoid these situations in the future. It's frustrating and makes me not want to see them.

Good luck!

they will advertise their high price on eros, TER, date-check, then use a different name, possibly different pics, and lower prices on BP or its ilk.  They prefer to fill their plate with the higher price, but want to get a full plate so they also take from the lower price buyers.  But, if you have an appointment at 200/hour and the provider gets a call wanting the same time slot at 300/hour, guess who gets bumped/delayed/told they need to wait outside in the car for a bit.  Nonetheless, if your willing to take/bear that risk, and are astute at spoting thses discounts, you can get great experiences at bargain prices - once the session begins, their instincts/habits take over and generally you get the same as a high price payer.
