Hi Cedge, welcome to the T-Shirt Forums!
Thanks for the link. Actually, this post is about a year old

Since then, I've found out that most of the time, it's easier to buy whichever blank you like (be it Hanes, AmericanApparel, Gildan, Fruit of the Loom, etc) and then have them relabeled by either your screen printer or a relabeling company (or local seamstress).
