I can’t stop chuckling over one of Amazon’s many marketing sleight-of-hands today. I awoke to email promoting a one-day sale and “up to 60-percent off select SanDisk products”. Heck, my BetaNews colleague Wayne Williams even wrote a news story. But based on my recent experience buying a “SanDisk Ultra 64GB MicroSDXC Class 10 UHS Memory Card” I wonder about all the savings.

I purchased the card on July 2nd for $34.99. For the one-day sale, Amazon sells the same card for a dollar more, although a newer version (e.g., refreshed packaging and SKU) is available for $31.99. Amazon claims 64 percent and 51 percent savings—$64 and $33—respectively.
