where can I get a SDHC photo card cheap?

These cards, from Transcend, let you do more than you thought possible: Store More Photos
With most point and shoot digital cameras quickly climbing the megapixel ladder, 6,8, and even 10 megapixel ratings are beginning to be commonplace. With Transcend SDHC cards, you can keep up with the larger files these high resolution cameras produce. With 4 GB, 8 GB, and 16 GB capacities, you can store more photos without having to delete old photos on the card before you have the chance to save them to a PC or print them out.   Store More of Everything
The larger capacities of SDHC cards make them more versatile than ever. Use them in all your mobile devices that support the SDHC standard. All that is required is an SDHC compatible slot or reader. SDHC is an extension of the original SD standard that enables capacities greater than 2 GB. It uses the same physical form factor as SD, but SDHC cards only work in SDHC compatible devices. Standard SD cards work in both SD and SDHC devices (backward compatible).   Enjoy Faster Transfer Speeds
Basic SD cards transfer data up to six times (6x) the data rate of the standard CD-ROM speed (900 kB/s). Transcend SDHC class 6 cards offer a minimum of 6 MB/s write speeds under the most demanding storage conditions. Some cameras require a high speed card to be able to record video smoothly or capture multiple still photographs in rapid succession. Check your device for maximum compatibility for your intended usage patterns.   Hope you capture some great memories!
