Buy.com offers the Kingston 2GB microSD Card 2-Pack with SD Adapter (4GB total), model no. SDC/2GB-2P1A, for $7.95. With free shipping, that's $1.99/GB, tied with last month's mention, and the lowest total price we could find by a buck (outside of the below offer).

Of note, Amazon has it for the same price for its Amazon Prime members. (Non-members can spend $25 or more for free shipping, else it's $5.58.)

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