just make an order for at least $20 worth of nonexpress liquid's
and in the comments section ask for a free sample of a
juice flavor list the mg and vg/pg(yes they do it backwards) that you prefer
Also make sure you check the flav you are going to ask for that it does not say no avail for samples
3 weeks after your first order they will send you a coupon for 15% off coupon
and ask for your feed back on the
juice and they will begin to design a flav profile on you to better suit your needs n the future
