I started with ordering the samples too.  I found that I saved more with the bigger bottles.  The samplers are $2.25.  That makes them $22.50 per 30ML.  Even with the discounts that get posted (let's use 25% as a guide), a 30ML bottle is only around $11.25.  It isn't that bad a deal and a pretty good savings.  Also, David usually, but not always, tosses in a free sample with every order.  You get more for your money that way.  Plus, any juices that you don't like can get traded in the forum for quite a number of samples.  I found that I had a ton of samples kicking around that I really didn't like and are harder to get rid of.  The ones I did like were gone way too fast.  Yes, I am an "economist" too but, I would call myself cheap.
