Amazon Prime Days are July 16 and the 17th.
For those who are not Prime members, I believe that you are allowed to sign up for a trial so as to shop during Prime Days. But as with any trial, be careful to cancel before the trial runs out.
Prime Days are often very good days to buy anything travel. I am aware there can be very good deals on luggage.
Myself I am looking for a cross body bag with anti theft protection. If I can get a good deal, I might go higher than I normally would.
