There's a new printable coupon out for $2 off any Visine (no size restrictions). Check out the Personal Care category on the left. Don't forget to hit the back button to print 2 coupons.
It's being reported Target has Visine travel size bottles for $1.99 which would make them free.
I don't remember seeing these in my store's travel section but I will check it out next time I'm there!
Thanks Totally Target!
