I forgot to add, that juice descriptions are important, I think.
The first thing I look for when shopping for juice is a very good description. If the description is thorough, I'm a potential buyer. If they are honest and accurate descriptions and I like the juice, I will most likely come back for more.
As you build, reviews are the next thing I look for. I don't ALWAYS shop by the number of favorable reviews, but it sometimes tips the odds in favor of a purchase, and sometimes causes an impulse purchase.
