AT&T are offering some big discounts on refurbished original iPad WiFi + 3G models. They’ve got offers including:
$329 for a refurbished 16GB WiFi + 3G iPad
$429 for a refurbished 64GB WiFi + 3G iPad
These are models that originally sold for $629 and $829 respectively if I remember rightly.
If you’re on the lookout for deals on the original iPad, for yourself or maybe a friend, you may want to check these offers out.
