I used swansons for years and then got disenchanted with them. Calif has a regulation SB something and swansons just stopped shipping some items I use to CA. Other suppliers do not, you normally just agree to terms of the SB....issue and they all ship to CA.

pureformulas ships everything free. iherb ships free with $20 purchase. Luckyvitamins and vitacost (charge sales tax to CA) one has to buy $49 worth of products for free shipping. Amazon normally $35 purchase for free shipping unless one has prime which I don't. i like webvitamins for a couple of my supps and they are $49 for free shipping, but with them they take forever to get to CA. i've used puritan but don't care for their pp quality and otherwise their stuff is more pricey.
