Ok. That’s too bad! If you keep an eye on Amazon Daily Deals, they often have sales on SD cards. You can get good quality ones now for less than $1.00 per GB.
Disclaimer: Unfortunately, Amazon.com has some seriously unsuitable images right on their front page. It’s too bad that there’s not any other place to get the occasional good deal, but that’s the way it is. Although, come to think of it, Walmart isn’t any better… đ
