I just did a search and found several, some for Vicodin, Dilaudid, MS Contin, OxyContin, Norco. I guess some people are buying them so they have a bottle to keep drugs in that didn't come with a prescription. Even if you actually have a script but don't have your meds in the bottle you can be in serious trouble. That would be my guess for the reason to buy and sell empty bottles.

Well looking they aren't even bottles that have been prescribed....it's not like they are old apothecary bottles so I don't know why they would be 'collectible'.....not sure about why people would buy this.
