I think you're going to like them. Most of the T-shirts I get from companies or websites are typically just a color or two. But the WinCustomize T-shirt has quite a few colors on it and the T-shirt itself is very high quality.
The hats in particularly though are what astonished me. They are REALLY cool. I'm a biased source but I don't think I've ever seen such good hats. Lots of colors embroidered logo, very good quality.
Now if we can just get the mugs. The mugs are more challenging. It may be a bit before we do that. 2 color mugs are easy, but lots of color mugs are tougher.
