(i posted this in the reg foum but realized it may should have been posted here - Sorry!)
If you go to this website their is a printable $1.50 coupon for 2oz purell - I have printed this coupon twice and used it at Walmart both times and bought the double pack of the 1oz bottles where one of the bottles comes with a keychain strap (says net 2oz on the front of the pkg even though it is 2 1oz bottles - they were up at the registers) They cost $1.94 so you get both bottles and the re-usable keychain strap for .44 - Not bad!
