128GB Lexar CompactFlash Pro 800x UDMA7 for $80, 256GB for $160, 512GB for $300

On the Lexar front, their 128GB CompactFlash Professional 800x UDMA7, model LCF128CRBNA800, is currently on sale for $80 with free shipping at B&H Photo and Amazon itself (limit 5) and Adorama where the 256GB version has the same price per GB as the 128GB ($160). But in terms of GB/$, the 512GB version defeats its line-up siblings at $300.

PRO TIP: since storage capacities are in multiples of two, you don’t have to do the actual math to figure out which one has the best price per GB. Simply see if the price of the next/previous items is twice/half than the current.
