We love us some cheap external storage here at Android Police, and today Amazon subsidiary Woot has a great deal on a jumbo-sized MicroSD card. The site is offering a 64GB SanDisk Ultra MicroSDXC card, refurbished, for $24.99. That's less than half the retail price of the new card, and a solid 35% off of Amazon's price. This is an ongoing Woot sale, so it won't disappear after today - the price is good until September 1st, or until stock runs out.
Woot is also selling a refurbished 32GB version of the card at $15, but since you can find a new version for around $20, that's not really worth the drop in reliability. Speaking of which, both cards come with a rather short 30-day warranty from SanDisk, not to mention the usual full-sized SD card sleeve adaptor to easily use the cards with cameras and laptops.
The deal is limited to three cards per customer, and as always with Woot, shipping is a flat $5. (You can add more cards, or other items currently offered in the various stores, without increasing the shipping cost.) Woot doesn't ship outside the United States, so sorry to our international readers. Depending on your state, you may have to pay sales tax.
