While I think Ryangripp is on the right track I'd also add that you should look at what type of technology is being used at each place and how it will help you move forward in your career. Look for companies that aren't just going to pay you more but will help you grow as a programmer.
Example. Shop A and Shop B are both working on software type X. But Shop A is stuck in the stone age of VB 6 while Shop B is moving everything to C# and starting up a mobile group. Even if Shop A offers you more Vacation Time/Perks/$$ I'd go with Shop B.
Reason: You need to think about what skills your next employer will be looking for and how this new job will look on your resume once you want to move on.
