I used to use iHerb for everything until they changed the way they do discounts. Vitacost frequently give me coupon codes allowing for 20% my order for example (and if I leave the items in the shopping cart a few days they email me with a further 10% code to finish the order).
iHerb is better at international shipping for smaller orders (because I can get it free) but VitaCost small orders cost only $10 and the promotional discounts usually outweigh the difference.
But I was wondering if there are any other major suppliers of supplements out there (that do international shipping) that people use
Out of iHerb or VitaCost (or another one) which do you prefer?
Any negative experiences that would prevent you ordering or recommending a company?
