Fast delivery on a great shirt

I've used alot of local tshirt printers and never been total satisfied with either the quality or the speed at which the tshirt were delivered. I've used sticker mule for some little fun personal shirts but this time I used it for shirts for my business. The shirts came in 3 days ahead of schedule and looked great, the shirts didn't shrink at all when I washed them and were very comfortable. My only issues are: 1) the shirts run very small. I bought xls and they are very tight through my shoulders, but I am on the more muscular side 2) I wish they had more color options in shirts, would love to see a yellow or military green, and the option to print on the back would be a game changer.
