Amazon offers Prime members the Purell Multi Surface Disinfectant Spray 2-Pack for $6.50 with free shipping. (Target has it for about the same with free in-store pickup.) That's tied with our mention from ten days ago and the lowest price we could find now by $2. It purports to kill Norovirus and MRSA.

Note: It's expected to ship in one to two months.

Update: The price has increased at Amazon; however, Target offers it for $5.62 when you add two to cart.
