Have shops show how many matching items are in inventory

[PlatinumSpider]

In the shop interface have a number owned show at the end of an item's line to let you know how many are in your inventory.

? a - 22 gold a scroll of identify (3 owned)
? b - 38 gold a scroll of magic mapping (unknown)
? c - 38 gold a scroll of amnesia (0 owned)

Also warn the player if another shop is offering the same item for cheaper

And let them buy it directly without having to backtrack to the previous shop.

How about just removing shopkeeper greed entirely? I seriously can't fathom what purpose it serves other than to encourage tedious behavior like this.

ion, It's so you can get a limited number of the item at the cheap price, but to get more/all will be more expensive, and you are more likely to run into interesting tradeoffs regarding which items to buy.

(In the long run, as non-gozag, you'll be able to buy all shop items. As Gozag you will always have the buy item vs open new shop trade off, just another reason why gozag is the best god)

PS: I'm not defending the fact that you have to backtrack to find the cheapest item.

Gozag is the best god because it's an opt-out from the tedious chunk-butchering game. The fact that's it's a powerful choice is just a happy side effect.

FR: implement dungeon market forces. The discovery of more/cheaper supply will lower prices dungeon-wide to match, but once competitors leave the marketplace prices rise again.

One implementation of "market forces" would be the following.

The "greed" parameter for most shops is eliminated. It's well known that the main thing for businesses is "location, location, location". Nobody needs to spend anything on advertising anyway. Since all locations are the same (modulo auto-travel), all prices should be the same (except for antique shops which sell unidentified items). If you can get to the shop, you can buy it for a fixed price. If there are too many monsters around (like Orc:2), you can't get to the shop at all, so the price is effectively infinite.

Shops in Bazaars can have the "greed" parameter, because their location actually matters (you can't travel in and out at will).
