CTC Store via Amazon offers the SanDisk 16GB microSDHC Class 4 Secure Digital High-Capacity Card, model no. SDSDQ-016G, for $4.27 with $4.50 for shipping ($0.55/GB). That's pennies under our mention from last week and the lowest total no-rebate price we've seen for a 16GB class 4 microSDHC. (It's also a current price low by a buck.)
