Codger is a three-footed sloth.  He has a challenging time buying shoes because the stores only sell the shoes in pairs. If he already owns the 3-piece set of shoes he is wearing, how many pairs of shoes does he need to buy to have 5 complete 3-piece sets of shoes? Let's think step by step and output the final answer after "####".

To have five 3-piece sets, he needs to have a total of 5*3=<<5*3=15>>15 shoes,
If he already owns three shoes, then he needs to buy 15-3=<<15-3=12>>12 additional shoes.
Since each pair of shoes includes two shoes, he needs to buy a total of 12/2=<<12/2=6>>6 pairs of shoes.
