I think some people here in this forum buy supplements from Iherb.com. I have tried both Iherb.com and Vitacost.com and I would like to share my experience with both.
I can say that Iherb.com is so much better (at least four times better if counted in days) in terms of shipping to overseas than Vitacost.com. With Vitacost.com, they use DHL Global Mail where the rates start at $12.99 for any weight up to 3.6 lbs. With Iherb.com, they use DHL Express-International where the rates start at $10.00 for any weight up to 6 lbs. The last time I ordered from Iherb.com, it took me only four days (ordered on Monday and delivered on Friday) to receive my order. Not only is DHL Global Mail much slower (as of 1st December 2014, it is now taking 18 days and counting for me to receive my items, though I can track my order online), I can't understand why it is more expensive than DHL Express-International, which allows any weight up to 6 lbs for $10.00 and I receive my items within the same week. I really don't know how Iherb.com can have such good international shipping rates from DHL but it certainly doesn't augur well for Vitacost.com! As a result, I don't think I'll buy from Vitacost.com in future.
PS. Iherb.com used to have shipping rates starting from $4 not that long ago, but it looks like they have raised prices to the current $10.00. Nevertheless, their shipping rates is still much better than Vitacost.com.
I have tried both Iherb.com and Vitacost.com, Iherb.com is much better
