There's some pretty nice Amazon deals going on just for today on Transcend SDHC, Compact Flash, and SDXC media today only. I've compared the deals to other big box retailers and though Compact Flash and SDXC media are also on sale, the most significant discounts are mainly on the SDHC media.
I'm actually using mostly Transcend media in ALL my cameras, and the 32GB SDHC Class 10 can handle video mode in the Canon 5D Mark III with ease, and it's on sale today for just $16.99 right now (click here).
