Contracts yet again

Hey all. Sorry for being a noob but this contract thing seems so over complicated and is bogging me down. Is there any such guide like "Contracts for Dummies"? I thought joining a Common Market would make life easier but after doing so I'm thinking different. Any advice would be appreciated.

They do seem to be somewhat complicated... but the best thing is that you don't need them! Plus, they can be damaging, if you buy them at a too high quality.

Generally, one only needs contracts to support his nuclear weapons plan.

Just cancel your contracts and rely on the open market to satisfy your needs. You just need to use a good "buy strategy". I suggest:
Start at 95% of the market price and increase by 5% every month that the product is not delivered.
