Walmart discounts a selection of 3rd-generation iPad models, as listed below. With free shipping on all orders, that ties last week's mention of one of these models and it puts each model at the lowest total price we could find by at least $170. The deals:

• Apple iPad 32GB WiFi + 4G for AT&T in Black (pictured) or White for $499
• Apple iPad 64GB WiFi + 4G for AT&T in Black or White for $559
