These are probably my four favorites, but I order from others also, like Dixondale Farms for onions.

Baker Creek (www.rareseeds.com)
Johnny's (http://www.johnnyseeds.com/)
Willhite (http://www.willhiteseed.com/)
Pinetree (http://www.willhiteseed.com/)

I'll list some different ones than Carol did, but her 4 favorites are some of my favorites too.

Sample Seed Shop (www.sampleseeds.com). This small company is owned and operated by a Garden Web member named Remy. Unless otherwise stated, her seed packets all are $1.50. Everything I've grown from her seeds has done exceptionally well for me.

Southern Exposure Seed Exchange. (www.southernexposure.com) This employee-owned and operated company specializes in southern heirloom varieties and has a wonderful selection. I could have pretty much the garden I want every year by only purchasing seeds from them (as long as I could keep getting my onions from Dixondale).

Victory Seed.(www.victoryseed.com) This is one of the first companies from whom I purchased seed online and remains a favorite.

Nichols Garden Nursery (www.nicholsgardennursery.com) Fantastic selection and all kinds of herbs (both seeds and in plant form.)

Swallowtail Garden Seeds. (www.swallowtailgardenseeds.com) Wonderful varieties. It is dangerous for me to stay too long at their website because I want to buy one of every flower variety they offer.

That's a few to keep you busy.
