Ladies and gents, given the price increases over the last few years, has anyone found a better pricing model on the basis of being a regular client?  For example committing, in some fashion, to seeing someone monthly?  If so, how was that commitment determined? How often are the visits? How was pricing changed?

I've paid less to see escorts that I've seen on a regular basis. It's her way of rewarding me for being a regular ongoing client and keeping me on her client list.

I think most women want to see a commitment first before they entertain any special arrangements/pricing. That has been my experience. See the lady in question a few times, make sure you are compatible both sexually and personality wise, and then approach the lady at that point.  
As to how that commitment is determined i.e. how frequent you see her, and at what price point, that will be determined on a case by case basis as some ladies are very agreeable to these type of scenarios and others, not so much.

I’ve seen a provider at least monthly for many years. She offered to grandfather me whenever she raised her rates, but I paid her going rate or even a little over because she’s one of the best providers in my area and her rate is reasonable.  She hasn’t raised her rate in over 5 years.  She sees only a few clients now (has another job that takes most of her time) so I’m fine paying what I do.  

that you are the one who's curious about this.  Lol   Good question.  I have done this with a couple of ladies that I was regular with, but it's tough to get if you're talking a one-hour session once a month.  I had a few ladies knock off 20% of the hourly rate if I committed to four hours a month.  For my own convenience, and to allow time to see other ladies, I usually broke it down into two two-hour sessions rather than four one-hour visits.  I don't think it mattered to them which it was.  

Same here, except for me, it's Great Grandfather Pricing

  When it comes to prices, the amount of session time (Amount of time by the hour or by the week or even by the month). That depends on each individual Provider. Some Providers will see what their schedule allows as far as time and where she'll be and for how long, then talk about the price for that amount of time.  You (The hobbyist) must take in account that the Provider (Who does In-Calls at a Motel/Hotel) has to make more money then what they dish out for Transportation & Motels/Hotels. We (The Providers) have to sustain our life style. Meaning, things such as a place to sleep & Shower as well as Food in our stomach, Clean clothes and etc. Don't come free or even at a cheap price.

On my site, I lay out both all of the arrangement options and requirements. But let's use the first group as an example:
For shorter dates (90 minutes up to a full day), an arrangement is available if you're planning to see me twice a month or more. And, this is kept as a month to month retainer. (IE-there's no expectation to invest say, 3 months). Arrangement rates are approximately 25% off (or, one full cost date, one ~half cost date, if you want to look at it that way). I guarantee commitment by requiring the full arrangement rate for the month (ie-both dates) up front on the first date. And, for those guys gasping right now, my clients determine my commitment (that I'm not going to run off with the cash) by setting strong precedent for being well reasoned and professional. It's apt that you mention the sugar world. I've had arrangements in the past, and there's a great deal I actually prefer about them from both a personal and a business standpoint. The problem is that most of the actual people in the sugar world aren't my cup of tea, for a whole variety of reasons. Arrangement offerings as a companion gives me the best of both worlds.

Used to be a thing, whether to keep clientele or garner new clientele.  I once saw a lady who later became one of my ATFs and she discounted the initial session. Now not so much.  Between deposits, the new woke crew, the old woke crew, and high priced newbies I doubt grandfather will ever be a thing again, it's just on to the next one who will pay the full rate.  Nowadays I think if you ask a provider if that program is available you're more than likely to be ignored or cursed out, or maybe even blacklisted.  I can say that I have dealt more with up-charging and increase of scheduled time demands than someone who grandfathers rates these last few years.  

That's a good business model. Wish others offered something similar.
