Target.com shows Purell 1L size for $6.49, but they’re ringing up at between 50-75% off in most stores. Use this $1 Purell printable to save even more; the 10% Cartwheel is not for this size. Check your location and save BIGL :)!  Use Brickseek to see if your stores have stock.  At my store they didn’t even have a shelf tag, but turns out there were 12 in the back, so make sure to check.  I paid $14 plus tax for 12 bottles.
