Sears offers the Samsung 51" 600Hz 1080p Plasma HD Television, model no. PN51F5300AFXZA, for $499.99. Opt for in-store pickup to dodge the $69.99 delivery fee. That's tied with last month's mention (which included free shipping) as the lowest total price we've seen. (It's also a current price low by $48.) Features include a native resolution of 1920x1080 (1080p), 600Hz subfield drive, USB, and two HDMI inputs.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
