Almost on topic:
A few years back my friend pointed out to me that no rub doesn't mean that you don't have to rub the contacts, as you are supposed to clean by rubbing every day. (Seriously, on each no rub solution, the directions still say to clean, and there are prob a few pshatim giving in "no rub") Still, I rarely clean them each night. Was wondering what everyone else does...
On price for solution, I was using WalMart brand for under $5 a bottle, until Costco had a coupon for the Kirkland one and it came out even cheaper!
Have not bought contacts in years as they last a while by me, but great thread, as I'm prob due a new supply around Pesach time!
