Adorama has SanDisk 8 GB Extreme III memory cards on sale. You can get a 3 pack of Compact Flash Memory Cards for $69 and/or a 3 pack of SDHC cards for $129. To sweeten the deal even more shipping on either set of memory cards is free.
Here are the details:
The 3 pack of SanDisk 8 GB Extreme III Compact Flash Memory Cards is $149.95, has an $80 rebate, making the final price $69.95 (yup, that's just $23 per card).
A 3 pack of SanDisk 8 GB Extreme III Secure Digital High Capacity (SDHC) Memory Card (Class 10) is $219.95, comes with a $90 rebate, with a final price of $129 for three cards.
I just checked the web site of another (well known) photography retailer and their price (after rebates) for the same SanDisk 8 GB Extreme III compact flash card is $45 per card.
These are the same cards I use (and just bought more of) and regardless of how fast I shoot I never have to wait for an image to be written (read/write rate 30 MB/s). Of course this is nice on the other end as well, when downloading these images after a shoot they go pretty darn fast.
Christmas is coming up fast and these (with a very well placed hint) would be a great gift.
