Food chain business

I have another question about an event.I have made food items such as
salmon,steak,wine,beer and so on.These items are sold in my restaurant
for gold.Now what I would like to do is be able to take these items to a different restauarant and sell them for a profit.Certain restaurants have
specialty foods and the price of the items varies in the different restaurants.Now the problem that I have is that I cannot change the selling price.I can make the guy take the food and give me more money but that is with the money management command and it restricts me to sell one at a time.Also is it possible with the variables to make the prices of items flux depending on how many you bought and sold of that particular item.Just a yes or no to the last part would be fine.
Thanks for your help bluecube on the last one.

You have some good ideas.

*SUMMONS BLUECUBE*...hmmm, magic must have worn out.

My game is already about 25 hours long tyrannicide.I have worked on it for about 3 months.I am just starting to work on the cutscenes and optional quests.

Is there a demo or beta tester???if not, i will if u want.

I was thinking of releasing a demo but my copy protect skills are lax.The only reason I'm hesitant is because if my game got ripped off and changed I'd probably smash my computer. The only thing I've done for the last 3 months or so is make my game so you can see my canundrum.On the other hand though I could really use some help with my optional quests if your good with variables and the such.Also the size of my game is a bit big and I dont know where to post it.It is around 90 mb.

I havent used RM2K3 in a lomg time. I use to test my bros games all the time and find errors and sometimes fix them my slf, other times I would tell him to change.

I like testing, im good at finding errors and such. Dont release a demo, most people that release a demo never finish the game.

Okay, I think I need to check the forums more than twice a day.

Anyway, there isn't any real way to change the selling price of an item within a game.

You can, however, set it up a custom selling menu (just like the one with the scales, only you're selling them instead of making something with 'em). Each store would pay different prices for different items. You could also set it up the same way for buying stuff.

The idea is to set a variable = number of food items of a given type, then multiply that by whatever the buying/selling price is. Do any checks you need to do (such as when you're buying, compare the final price to your gold) and it shouldn't be too hard. I'll build another demo if you really need it.

I think that will be good enough bluecube.I have already started to work on the food chain.So far I havent ran into any problems.If I do bluecube I'll let you know.
