Pupster, you haven't had contracts law - I have. Contracts are not specifically enforceable the way you PRESUME they are when economic damages are measurable.
Look up some terms today as a start:
compensatory damages
expectancy damages/expectation damages
reliance damages
consequential and incidental damages
liquidated damages
specific performance
lost profits damages
Just for kicks - start here - Hadley v. Baxendale is one of the first cases you study when you get to damages/remedies - it is not exactly on point here, but it'll give you a flavor for why your ideas about how contracts bind parties to literal performance terms is laughable.
Then, when you're interested in contracts for goods, start with the UCC.
