Ipads

Apple only carries current models in the Apple Store or physical Stores. Subject to stock availability, older models of iPad might be found with Apple Authorised Retailers.

Reconditioned models may also be available from both Apple and Authorised Retailers.

This is a user-based support community - users helping users. The iPad mini is still for sale on the Apple Store, but I don’t see an option for the 128GB model.
