Sdm & sof

So I think I did this right at SDM - could someone check my math?

15x Gillette shaving foam/gel: 2 for $5 - (5x save $5 wub 3) = $0.83 each?
4x Tide: $4.77 each - (2x save $3 wub 2) = $3.27 each

I think I might be wrong with the shaving foam - my math is messed up because one gel rings in as $2.01 and the next as $2.99 and the last one was $2.99. I'm thinking I should have only gotten 12?

Then, on to SOF:

8x bacon BOGO = $4.99 x 4 = $19.96
6x delissio pizza = $4.99 wub 3 or more = $29.64 (we like these for Friday nights).

And we'll be hairless for awhile, anyways. :>
