I am going to order a sample pack of five 5ml bottles of e liquid from wordup. the cost is about twenty dollars. first question is this a good price being aware I may like all five or not like any but will have that info for future reference. also what is the difference between USP grade propylene Glycol-kosher 99.9 percent pure food grade and 50/50 mix pg&vg 99.9 % pure food grade.
that all might as well be in a foreign language to me. Ha
