Spring Cleaning?? - Windex - $1 Printable Coupon

Ok..I confess.  It's summer and I'm a little behind (well, maybe a good bit behind) on all the spring cleaning plans that I had...BUT  I just came across this coupon on coupons.com for

$1 off ANY Windex product.

This has me fired up again, so maybe I'll get something accomplished today.
