I find that it's feast or famine. I'll go half a year or more without seeing a provider (grow some sideburns on my dick
), then I'll see 3 in 3 days. My travel schedule and the level of available talent at that location seems to drive it.
I have to stay under the radar, which means slowly accumulating funds, and since that takes time I don't think my frequency can be effected significantly. If I had more money, then I could see more ladies more often, but that ain't gonna happen. Discounts are ok, but there is only so low you can go before you either pickup the wrong clients or loose quality providers, the ladies I see are usually in the 250 to 350 range. For myself, the tipping point would be SERVICES offered; all else being equal, a lady that costs the same as the rest on the site, but that does greek (no upcharge, or low upcharge) seems to catch my attention, and gets me to call. Also, if her price is slightly higher, lets say 400 (including greek), then more time can also sometimes get me in.
In Toronto many of the big agencies do volume discounts within a set period of time (usually, buy 4 get 5th free or at half price, but the window is like three months), seems to work or them. I guess that way for those that offer discounts you still keep the clientele and the ladies upscale.
I would recommend all of the above, used in combination. Different girls offering different levels of service at different price points are likely to do better under different incentives.
