Well, they're all discounts, for starters.
Surveillance pricing defenders claim that surveillance pricing is better because it works both ways--it might offer a higher price to someone who is desperate, but someone who is likely not that motivated might get a sweet deal. I highly doubt that. A highly-advertised, transparent discount or sale is how you sell to someone who is not that motivated. Surveillance pricing is how you (secretly) extract as much money as possible from the desperate.

And they're subsidized by the revenue made by everyone else. A thousands of coupons start rolling in and meaningfully affecting revenue either the coupons go away or the MSRP increases. It's the exact same pig just slightly different lipstick.
Is it just a matter of the 'turbo' button then? Surveillance pricing could be reframed to be entirely discount based. A banana shall be $10k/unit and then it is discounted either $9999 or $9998 depending on who you are? It seems fairly equivalent. I don't like it either because I don't want the vendor to extract almost all the surplus from the relationship but I suppose I could get that by just settling for fewer things and only buying where the price does not capture surplus.
