There are so many places that you might consider either "Google" or "Bing" (which I am starting to really LOVE!). In "Search" type something like 'wholesale t-shirts' or 'wholesale totes' etc. You will find lots of blanks.
www.AllAboutBlanks.com has a wholesale section which you can find at their site. The quality of their products are very high for the most discerning of persons.
