Amazon offers its Prime members offers the Transcend 32GB SDHC Class 4 Secure Digital High-Capacity Card, model no. TS32GUSDHC4E, for $21.99 with free shipping ($0.69/GB). (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $8.05.). That's $2 under our December mention and the lowest total price we could find by a buck.

Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months.
