While at WalMart today, a friend wanted some spray lens cleaner for his glasses. There were two sizes available and he picked the large. The lady behind the counter told him that if you buy the small one you can take it to any WalMart optical department and they will refill it free.
All of the Sunglass Hut kiosks in malls do this too. If you buy their little kit with spray bottle of lens cleaner, eyeglass screwdriver tool and cleaning cloth, they will refill the bottle for life. It costs under $10, comes in very cool designs of cloth and incredibly cool hard or soft sided carrying cases for the kit...some with rhinestones, other masculine leatherlike and some fancy drawstring typea in lots of colors.
