Are you sure that's the free Best Buy case? I saw that particular one you describe advertised in the Circuit City ad.
Firstly, I should make it clear I didn't get an SP from BB, so I may be totally wrong, but... The only cases I saw at BB--where the SP's would have been--were Pelican brand "leather" pouches in a very nice plastic box. But for something that they sell for $15 otherwise, it is devoid of nicities. All it is is a pouch, period. Slip it in, slip it out. No fold over flap, no belt clip.
