Nub question about MTS

Never used it before, so something I don't get.

For "Price (no.)", if it says something like "221/3", does that mean that the given person has three of the same item offered for 221 each or does that mean I will get 3 for the price of 221 NX?

second option (assuming you are buying). for someone to sell three for 221 each they would make three entries, each for 221.
