You never really know what to expect when fishing for a new phone at Best Buy Mobile. Go in one week, and you'll see a strikingly pink Instinct for a strikingly large amount; go in next week, and you'll see the miniaturized version of the original Instinct for under 50 bones. If a new flyer is to be believed, the Samsung Instinct S30 will be offered up for just $49.99 on contract at Best Buy, which is a whopping $80 less than what Sprint itself will supposedly ask for it on April 19th. Too good to be true? We're hoping not.
