Get a 16GB microSDHC card for $25.59 shipped
Need some extra storage for your phone? This card works with most models and sells for less than half what you'd pay in an electronics store.
One of the things I like best about Android-based smartphones (even lower-end, no-contract models like the Samsung Intercept) is their expandability. Most can accommodate microSDHC storage cards of up to 32GB. You could have one for music, another for movies, a third for documents, and so on. Take that, iPhone!
Alas, 32GB cards are extremely pricey; the sweet spot right now is 16GB. Of course, just how sweet depends on where you shop. Walk into your local Best Buy (or similar big-box store) and you could easily pay upwards of $60 for that kind of storage.
Take it from me: storage is always cheaper online. For example, Newegg has a 16GB A-Data microSDHC card for $25.59 shipped. That's the lowest price I've seen anywhere for a card of that capacity.
There's not much to say about the A-Data other than it's a Class 2 card, meaning it delivers a minimum performance of 2MB per second. If you're willing to spend more, a Class 4 card will net you 4MB/second; a Class 6 card, 6MB/second; and so on. When it comes to smartphones, I honestly have no idea if those speeds matter one bit.
In any case, the card comes with a limited lifetime warranty. If you're looking for a big storage boost for your phone (or some other device), here's your chance to grab it on the cheap.
Bonus deal: More e-book goodness! SonyStyle has the refurbished 6-inch Sony Reader Touch for $89.99 shipped (you'll see that price once you add it to your cart). Usually it's the 5-inch, non-touch-screen model selling for that price (if not more), so this is definitely a steal.
