Price is really irrelevant, you should go by market cap instead. The market value of borders as a company at 20 cents is minuscule compared to its asset base and revenues. Anywhere under 20c is a buy if your betting on shares being saved, heck anything under a dollar. Its pretty safe to assume 20c is fair value right now because it say there for days while the bk filing was being prepared.
Its more about executing a proper averaging down strategy if playing a bounce is your game as well, base your purchases off the market cap and don't play with what you can't afford to lose.
IMO and good luck to all
