I know you are not to discuss prices. But what if one ad there is a price. But on another ad there is a different price, there is $150 price difference. Do you just come out & ask or what do you do without throwing up any red flags?

And NO she does not have a web site.

I don't suppose this is a well reviewed provider?  
I really have to suggest newbies sticking to well reviewed providers.  TOFTT just has too much risk at this stage of your hobby career.  

IMHO, I've found low rates...  below the local market...  are for lesser time or service.  So you end up with an upsell girl.  I don't care for girls who scam...  I pass.

If not, then you should pass, but if you really, really must, then when you contact her tell her that you saw her ad on the site or whatever with the lower price, and leave it at that.

Caution if she has no web site.

More caution if she has no reviews.

But if you're set on seeing her respond to the ad with the lower price (reference that is where you saw her ad).  Just make sure it's for the same thing (time, city, dates, etc.)

She is very well reviewed, lots of reviews & date check certified. Also the people that reviewed her has lots of reviews. The reviews have one price & the ad on date check has another price.

Lots of providers give a discount if contacted/screened through DC.  If that is what it is (lower DC price) contact her that way (assuming you are a DC member).  It makes screening easier most the time and gets you the discount.

Compare US prices to Canadian prices in cities across the border from each other.  US prices used to be double.  Generally selection & quality's the same so I attribute most the price dif to risk.  Wacko client risk is the same so it's LE risk mostly.

If she can reduce her risk because you're DC screened it justifies reducing the price in many provider'e eyes.

now if the DC price is higher pretend you never saw that DC post!  

If the TER reviews have the lower price and she has reviews going back away, then likely the TER reviews are showing the original first reviewers price from a long time ago. I only ever use a TER profile price as a ball park guide. Unlike her ads most profile prices were not put there by the provider.
