In stores only, Radio Shack offers the Eye-Fi Connect X2 4GB 802.11n Wireless SDHC Secure Digital High-Capacity Card
, model no. EYE-FI-4CN, for $10.48
. (It can't be ordered online, but you can check local stock by clicking on "Find It Nearby".) That's tied with last week's mention as $15 under our mention from April (when we saw it bundled with an USB card reader) and an all-time price low for an Eye-Fi WiFi SD card. (It's also $17 below the best shipped price we could find.) The wireless SD card stores pictures like a standard SD memory card, but it also uses WiFi networks to automatically transfer images from inside your camera to your PC or Mac.
