Quaker Rice Cakes at Walgreens For .49 Each

This week Walgreens has the bags of little Quaker Rice cakes on sale for .99 each.  There is a $1/2 Printable Coupon available as well, that makes these only .49 each (this is a good price for these).  The other day when I was working on my Walgreen's deals for this coming week, I tried printing this coupon and couldn't get it to work, but I tried again today and was able to print off two copies of it.  If you experienced problems earlier as well, you might give it another shot.
