I saw on SlickDeals that Newegg is selling the Transcend 8GB Micro SDHC Flash Card (Model TS8GUSDHC6) for $14.99 shipped. (No tax in most states.) It's the cheapest price I've seen for an 8 GB microSDHC card with Class 6 speed. It's got great reviews. You can further sweeten the deal with Bing for 2.5% cashback (comes out to 37 cents).
