Cheap printing, anyone?

Recently I've been toying with the idea of getting some reusable bags and printing them as giveaways. But I don't know where to find the cheapest printer nor the supplier of such bags. There was this particular printer that we used to do poster printing that charged us at very reasonable rates, but not sure if the rates would stay the same some 4 years down the road now.

Maybe I should just give a call and find out. If I do get cheap rates, I'm just afraid I might still be indecisive on whether I should spend that kind of money.

Fickle, fickle, fickle me!
