San Mateo-based CafePress revolutionized the customized merchandise industry by making it easy for anyone to print their own artwork, logos or other designs on t-shirts, posters, stationary or any other on-demand product—and sell it. You can shop by price point or take advantage of sales items to get the best CafePress deals. Email list subscribers enjoy exclusive CafePress coupons, and flash sales (good for a short time) are offered frequently.
