Need more memory cards? OK, who doesn't. The Sandisk Spring 2010 Rebates (.8MB PDF) might be for you.
Check out the great 2-Pack deals at B&H and Adorama.
I especially like the SanDisk 32 GB Extreme Compact Flash 2-Pack at Adorama for $300. Jeff likes the SanDisk Extreme III 30MBs CF Card on special for $24.95 (reg $34.95).
