Coming Soon: Toilet Paper Priced Like Airline Tickets

If others find that agreeable, then they raise their price too. The desire to be in the "buy box" drives prices down, but this kind of maneuver would act as a reset mechanism.
As a counterpoint, the sheer number of competitors will help mitigate this.
For example, I just paid about £410 for one year's comprehensive car insurance with Aviva, via a broker, via moneysupermarket.com. When I went to Aviva direct they quoted me £950.
This makes some economic sense, but as a consumer I just hate it. It makes apparently simple purchases really hard work. (In a similar vein, in the UK it's often possible to save 50%+ on a long-distance train journey by buying a number of tickets covering various parts of the journey, even if you're staying on the same train throughout).
Yup, that's the crux of the matter and it is on purpose. Pure market segmentation as explained by Joel Spolsky[0]. They want to capture the surplus from the <rich or lazy or inept> who can't or won't check the prices while keeping the price-aware customers.

My take-away: this company was playing psychological mind games with me, was tracking my purchase decision (via UUIDs on the coupons, despite my paying with cash and not using a data tracking card.
2: The products offered at such discounts are generally higher price and offer little if any utility, or just plain crap (e.g.: processed foods you're better off not eating). You're better off buying store-brand, generic, or raw produce.
Decision: shop somewhere that doesn't play mindfuck with you, and/or is conveniently located (time + travel expense + product wastage are significant procurement expenses), and offers a consistent fair price. Extending extreme effort to shave a fraction of a percent off price (or spending several pounds to save several pence) really doesn't pay.

(It makes sense for Amazon to think about the price, they are going to sell it thousands of times at that price. But you only buy a case of toilet paper once a year, and it's going to cost you at most $30, so it's not really worth your time to figure out how to save eighty cents.)
The cognitive weight of that decision making is higher than a consistent and satisficing heuristic (shop somewhere that doesn' tplay mindfuck with prices and prices fairly).
Why does Amazon not provide this service to sellers? It seems similar to bidding for keyword-based advertisement.
