I used Customink years ago, but in hindsight, it was more expensive than it needed to be. Finding a good printer will enable you to get better quality items at a better price. I've seen too many people that always opt for the cheap white T's and one color printing, but IMO, if you want your product to last (I give them to my clients and they're one of the best advertising investments I've ever made), you invest a bit more.
I'm in NY, but I've been using a printer in FL for the last 6 years. Once he realized I would be a returning customer, he offered better rates. Hence heavy weight shirts (sweatshirts, ladies tanks etc) with multi color printing on fronts and backs, and costing less than half what you would pay at CustomInk or many of the larger companies.
