For what it's worth, I own 2-3 shirts from ChiTownClothing. They're good quality, good price, and if there's EVER an issue, the company is great about fixing it immediately. Hell, someone on CCS a year or two ago got a shirt that had a small hole in it, and the company paid for it to be shipped back, replaced it for free, and if memory serves me correctly gave them a discount on their next purchase.
If you like the shirts, buy one. If you don't like 'em, that's fine, but unless you actually own the product, there's no need to ***** about it. This is a good business for fans, and for posters of CCS.
The next time this company has a free t-shirt giveaway for this site (which they've done in the past), don't enter if you have that big of a deal with t-shirts. Go spend $40 on a shirt w/ a logo.
