For vapers on a budget, who don't have a credit card, and/or don't shop online, don't have a brick and mortar store nearby (my metro is over 300K but no dedicated vape shop...just tobacco stores that sell kits and prefilled, screw on cartridges of varying quality)...yeah, that's going to be the downfall of many failed converts. I watched one friend relapse at a party when he only brought one half charged up stick with him...nearly as soon as he got there sure enough, the battery light started blinking. Next thing I knew he was bumming cig's. He's since prepared for that after buying multiple batteries and juice online...no cigs for 9 months, and I'm very proud of him! But yes. Without the right tools, pre-planning, etc. it's going to be very difficult to make the switch.
