While prices vary depending on the state, popular brands like Blu e-cigs sell disposables for about the price of a normal pack of cigarettes. NJOY sells a 3-pack of its disposable cigs for $26.97 online. The expectation is that you get more "puffs" than you would out of a normal pack of cigarettes. You can shop online, but also many disposable e-cigs are available at gas stations or convenience stores. The vaporizer e-cigs tend to cost more, but they last longer and have a wide variety of flavor choices. Here in New York City a "custom" vaporizer starter kit typically is available for $50.
