I used shirtsupplier.com
there's a frequent buyer discount code you can use too - FBP8. It gives you
$3 OFF > Subtotals under $150
4% OFF > Subtotals $150 - $499
7% OFF > Subtotals $500 - $999
10% OFF > Subtotals Over $1,000
They do have a restocking fee and they suggest you buy a % more than you need to allow for defects so you have as many as you need at at the same time. I bought 24 of one color and they were all fine. I also bought some women's shirts - much smaller than the adult men's. I found the adult male shirts to be true to size after I washed them (in warm water). I bought Gildan and Hanes brands from them. I only bought 100% cotton.
