Walmart trip... No price matching

I ran over to Walmart to get a few little things today.  I started off with a just an idea what I want to do but I was not sure if it would work.  When I go to a store I always have two plans.  The first plan would be if every thing is in stock then the trip would be under 5.00.  The second plan is aways if things are out of stock and would cost under 10.00.  I got lucky and I was able to go with plan A.
