So there are dozens of online and e-stores to choose from these days and it is hard to figure out which ones to go with, but after quite a bit of searching, I am sold on iherb. I'll just go through my experiences:
1) When I first became a customer, I found a discount code for $5.00 off my first purchase. It is MER594. You can also use MER594 if you're a new customer to iherb and get $5.00 off of your first purchase. That alone was a great deal.
2) Large discounts beyond the initial $5.00 off--most products are reduced by %25 to %35 percent. In my opinion, they were unbeatable prices.
