Would be great of the ones who ordered something give me a feedback. I'm always curious about the quality of the final product. What I know so far:
Spreadshirt: The cheapest T-Shirts are good. Usually they are Gildan. Unless you want a special shape or color they are fine. The cheap sweaters (Fruit of the Loom) on the other hand are not that great.
Pixels.com: The pillows are awesome. Print quality is great and the fabric has proven to withstand a three-year-old. Order without the filling and get one (with coupon) for cheap at Jo-Ann's. I feel their prints are rather expensive.
Redbubble: The travel mugs are good but due to the shape it happens that the print stretches. I heard the bed duvet covers are good too. Well, for the price they better be! People order a lot of stickers and so far no returns. So they can't be bad. To be honest right now Redbubble is my favorite. Everything comes in a cool box with a card, which makes it really nice for presents. Spreadshirt orders come in a dull white plastic bag. Same with Pixels.com (aka Fine Art America)
P.S.: If any of you want text added on your shirts send me message. Spreadshirt charges for anything you add to the selected design extra printing fees even it's on the same place. I seriously don't get that, since I'm sure in the end it's just one print. I can do that plus it will look nicer than created with their editor (for reference try
