Cheap Spray Sanitizer

Wife stopped by the Bel Air Dollar Tree today. Cashier said just two customers yesterday bought 300 bottles of hand sanitizer, and now there is none. She also said there were lots of empty gaps in the shelves of who knows what items.
My guess is either Hornady A-Max or Hornady ELD Match.
The two have very similar profiles, but you might be able to tell if either matches yours.
I believe Hornady discontinued the A-Max after the ELD Match came out, but there are some leftover A-Max's for sale here and there on the web.
