This week, as part of their July 4th sale, Office Depot has SanDisk 2GB MicroSD cards on sale for $29.99 (final in-store price). That's $5 cheaper than at Comp USA, BTW.
However, if anyone needs regular SD cards (for a digital camera, for example), Comp USA has a PNY 2GB SD Card 2-pack for only $39.99 this week! That's 50% off their regular price for two 2GB SD cards!
If I see any better in-store deals, I'll post 'em here.
