Geeky Branded Apparrel Sources

Factual Questions

One of my co-workers got a TiVo t-shirt for his birthday. I went to the TiVo website and ordered a few, as my wardrobe needed updating and they were inexpensive.

I was wanting some help in pointing out other geek-devices that have advertising clothing at reasonable prices (<10USD per shirt) .

Mods. Feel free to move to MHO if warranted.

I had already looked at think geek, but their clothing is not subsidized by marketing, so it is over my limit. The TiVo shirts (incl shipping) were 3 for 25. The cheapest geek one is 10.
