The black Friday Deals on 16GB, 32GB, 64GB and 128GB SanDisk Extreme cards are great right now. The sales prices are very tempting. If you have a shoot coming up and need to gather up a lot of memory cards, now could be a good time to stock up. I’ve just added 2x 64GB cards to my cart. That should keep the Canon 6d going for quit awhile once it finally shows up next month.
