It’s cold and flu season — not to mention, be around people season — so put the fear of God in germs that venture near your hands. There’s so much Purell on sale on Amazon right now, you could affordably fill a vat and completely submerge your body in hand sanitizer (don’t do that though). Instead, just take advantage of these deals, and ensure that you’re armed with germ killer the next time a rouge cough or sneeze comes hurtling toward you.
