13.20 or 12.88

I did 2's on my finger and got 10 on one hand then added the three other bottles and got 1 leftover.First we took 0x2 then 0x3 then 0x1 and got 000 then we dropped the 0 and did 1x2 then 1x3 then 1x1 and it was 13.20 then we added the 2 numbers together and got $13.20 with 1 leftover or 13.20-1.32=12.88
