Q: how to permanently delete purchases

I already did that.  I sign out & back in and the automatic downloads that are available start.

I went through hiding the purchases.  I sign out of itunes and then back in.  The HD versions of the episodes start downloading.  I was told that itunes needs to delete my available downloads from the queve.

I did not purchase a subscription or season pass.  I purchased tv episodes and did not have HD on my kindle and don't need those versions.  If I went ahead and let them download it would take a week for all the available HD episodes to download because of our internet speed and this will cause a data overage on our bill.
