Can you save this much with kids?

Last night I went grocery shopping with the kids and bought 2 books of stamps, 10 boxes of seasations, 2 boxes of nutrigrain bars, 2 boxes of butter, 15 bottles of powerade, 2 gallons of milk, 2 half gallons of chocolate milk, white wheat bread, 2 big bags of snyders pretzels, 2 bonus packages of crest pro health with full size mouthwash and 2 boxes of yoplait gogurts all for the grand total of $17.78. The stamps alone were $17.60. I took the kids with me only because I prepared my list the night before. I had everything printed, cut and circled before we left for the store. Today I am going back to the store because the pop-tarts are bogo and C has been asking for them. We finally ran out from the last stock up sale. Today I am going to organize all of my coupons. I feel so overwhelmed and I know if I organize everything, I will feel a lot better. J took the kids to a play date at Great Explorations in St. Pete. We get in free with our MOSI pass.
