iHerb is offering two types of Vitamin D3 for free. (All prices quoted are USD)
21st Century Health Care, D-1000, D3, Extra Strength, 1000IU, 110 Tablets
Normally $5.99
iHerb Nutritionals, Vitamin D3, 5,000IU, 120 Softgels Normally $9.99
These are 1 per customer and 1 per - You cant order both.
Some have questioned the need for 5000IU so if that concerns you then order the 21st century product with 1000IU
As with all iHerb products its better to order more items so you get advantage of combined shipping which is $4 for 4lbs. Although they do ahve a DHL special shipping of $8 as already mentioned here at Ozbargain (search).
If you are a first time user you can use my referral code which can save you $10 off on your order, or $5 if the order is below $40
A referral code saves you and I get benefit as well.
Another great product to look at is their Stevia offers by NOW foods
$3.95 down from $8.95 but limited to only 1 at that price. BUT this is per flavour, so you can buy one of each flavour. I have tried most and like the Tropical fruit, Blueberry pomegrate, coconut, all in water or sodawater, 5-6 drops per large glass gives a sweet flavoured drink.
The Dark chocolate works great in coffee to give a mocha flavoured coffee,

As a side point. iHerb wont ship products with Xylitol, but customs have now changed the rules, and these can now be imported. I have advised iHerb of this and hopefully they will raise the ban at their end.
