You see the can of air to the left? Can anybody tell us why this costs between $7.99 and $12.75? It's a can of air to clean off computer screeens and keyboards. A spray can of just about anything else - paint, cleanser, wd-40, bug spray, goo off, etc - is less expensive. Office Depot sells a pack of three for about $15. We discovered something a lot cheaper. We put our lips together and blew "free" air onto our keyboards. It worked great!
