More grocery savings

I bought some Gatoraid for $3.99 and priced it at $6.49 at my usual grocery store. I guess they don't consider it food because it is surprisingly taxed, which is bad for the real me and good for the double project (because I saved even more). I also bought some mayonaise for $2.97, which I priced at $4.79. This all comes to a gain of $2.32 for the project. I am creeping up to the finish. I wish there was something I could just buy and get it over with, but there weren't too many good deals this week. I guess I am starting to be stocked up with all the non-perishables we use so this method may slow down soon. Only $7.47 to go and then I am done level 15!
