Great deal on Visine

I was interested to read once that one of the most requested items after a natural disaster was eye drops.  Made sense after I thought about it.  I've been watching for a stock up deal on them ever since, but hadn't found one.  But there's a great deal this week!  Walgreens has Visine on sale for $3.99 (I think it said regularly $6-7).  There was a buy 1 get 1 free coupon in Sunday 1/6 newspaper for Visine.  That makes them only $2 each!
