Walmart is already selling e-cigs in my town; unfortunately they are the pricey auto batteries with very limited capabilities ... probably more profit margin for them.
Unfortunately as far as a 1 stop shop, it just doesn't exist. Most of the vendors are small businesses who cannot afford to make a bad decision when it comes to stocking the store so they purposely chose very conservatively. You can't blame them for that but it is frustrating when trying to locate a popular product sometimes. While you can go the China route, they often won't offer a lot of the products direct to consumer, not to mention it can sometimes be a crap-shoot ordering from them. The prices are good but shipping can take a while and customer service, well, let's just say it could use some improvement.
