Does anyone have any suggestions for finding prefilled 510 cartomizers. I found some at vaporkings.com but not a huge selection. Most sites seem to just sell them in generic flavors of "tobacco" and "menthol" (neither of which I like) or just blanks that you have to fill. I really prefer buying the prefilled until I get better at filling the blanks myself. I just find filling/refilling a hassle at the moment. Any suggestions? Can't find anything on the forum or online about where to find them.
