Whether you're shopping for yourself, buying a gift, or just like checking out t-shirts, Day of the Shirt can help. The site collects the current deals from daily deal sites around the web and puts them all on one page so you can browse them easily, see their prices and click through on the designs you like.
The site is kind of a deal aggregator just for t-shirts, and includes offerings from Shirt Woot! and TeeFury. Of course, the site works on commission, so if you purchase after clicking through, the site owners get a small commission, but that may be worth it to be able to bookmark one site and shop over a dozen different shirt deals at once.
