You are supposed to get 1 SB I believe for each one you use but I have yet to notice whether I have or not. The SB's would be nice to get but I am still saving money and it is not worth complaining about to me.
Just like SB's are supposed to awarded in 2-5 days for shopping at Shop & Earn. I received an email and it is about a month before I will actually get them.
I just went and looked at my history and my coupon SB's were added 11/15/13.
