Thanks for the post. Amazon also has the same card and price.
One comment on the 30mb/sec speed - it is read speed only - not write speed. 30mb/sec is not very fast and you may be better off spending $11.50 more for the 45mb/sec Extreme card.
As always, there are lots of counterfeit cards so be sure to buy from a reliable source in SanDisk packaging. Generally Staples is fine, Amazon is fine, Amazon merchants need to be looked at closely, and be very careful with eBay. If the price is too low to be true, you may have a counterfeit.
