The drive's not available directly from their web site, but you can check availability for your local club online. If you're ordering more than $250 of stuff, you can even have them pull it off the shelves and hold it for you. It's an awesome service if you buy a lot of stuff at Sams.
Sam's site has a couple problems - one, it tends to have problems pushing up pages. Fortunately, the refresh button will usually bring them up on the second try. Two, their links are really poorly marked, and difficult to find.
Go to
www.samsclub.com. Click on "Click 'n Pull" to bring up the Click 'n Pull page, then scroll down to where it says Guest Preview, and click. Click on your state, and choose the store you want to check. Once you've chosen your store, enter the SKU, 294614 in the search box. It'll show pricing as $139.98, but it'll ring up at the correct price.
