Buy.com offers the Kingston 4GB SDHC Secure Digital High-Capacity Class 6 Card, model no. SD6/4GBKR, for $4.95 with free shipping ($1.24/GB). That’s a buck under our mention from last April and tied with our September mention as the least expensive 4GB Class 6 SDHC card we’ve ever seen. (It’s also a current price low, outside of the mention below, by $4.)

A close price: J&R charges $5.99 with free shipping ($1.50/GB) via its free Friends with Benefits Program.
