J&R Electronics has a fairly easy-to-use site, with product features and shipping charges plainly explained on each product page.  I've got to hand it to J&R Electronics, they really know how to deliver low discount prices.  When you click any product link you see below you'll land on J&R's page for that product, and you can continue to search their entire site for whatever you like.  A new window will also appear, showing J&R's current special deals.
