GS Superbomb bottom cap/spring lost

[Will P.C.]

I bought this piece of junk GS Superbomb GS-Superbomp 1600 mAH Variable Voltage Electronic Cigarette with LCD Display/2.5ml 312-1 Atomizer - Light Gray before I knew any better. The bottom is plastic and that broke off and then I lost the screw/spring thing.
Does anyone know where I can get a replacement?
