I used to order some of their products from Amazon, but it's cheaper to order directly, and they have a "Deal of the Day" which isn't usually what I'm looking for (but sometimes it is) but it's a good way to try a new product for a lower price.
Plus, they always add a little extra to my package. I've received small samples (usually of the Valerin) or full bottles (usually of vitamins).
I had a question about the various Omega blends they sell, and the customer service person I spoke with was both knowledgeable and friendly.
I like that they don't overwhelm me with emails, though I wish they would send coupons or discount codes once in a while. But their prices are already good and shipping costs are low--never more than $5.99 and free if you order more than $49. Since I usually order several different products and I stock up for a few months, I always get free shipping..
