be careful, i know walmart only sells 16gb iphones at some stores (at least the ones around here)
so im not sure of their iPad situation.
They had 64GB models when the 2 came out. They had 32GB when the 4 came out. They may have had others, those are just the ones I happened to inquire about. So they should have more than just 16GB models.
Does the discount extend to the more expensive models as well?
