Gotta compare apples to apples. We don't know what kind of fruit you got, if it's of the loom, you probably paid too much!
I'd suggest finding local distributors first cause most places do not offer free shipping, or have high quantity requirements (700+), or restrict you on which colors are valid (ash and white almost always disqualify you). You can find local distributors usually by contacting your favorite t-shirt maker and asking them for a local distributor. You will most likely need a resale license, which you should've gotten when you started up your company. Of course, local dealers oftentimes don't have all the products, so you still may have to go through another company or online.
If you feel the need to go online, then I've used
WASATCH - Tees of Atlanta in the past with good results. Forum members also commonly mention:
TSC Apparel www.sanmar.com BlankShirts.com - Wholesale Name Brand T-Shirts and Apparel www.alphashirt.com
I suggest dealing with your local distributor though, it's not only a place to get t-shirts with no shipping and handling, but it could also be a networking opportunity to let them know what you can do and possibly have them send clients to you.
