I didn't see the 20% off but I did find the $80 off iPad Mini Retina... I wonder if that 20% will hold after the expected price adjustment once the new iPads are out.
I want a mini, but all the discounts I found were only for the other models, never for a mini retina.
Maybe with lagging sales and a new model and more competition, they'll finally come down in price.
I really think the mini is the right size.
