Vistaprint
I was determined not to spend a lot of money on invitations and the like. Although they're an incredibly important part of the wedding, I know not many people would keep them so I didn't want to spend thousands of dollars. Instead, we went to Vistaprint where I get our annual Christmas cards. Their invitations and everything to be included are beautiful and incredibly well priced (plus we have a couple Living Social deals for them) and they aren't costing us an arm and a leg!
