Why don't you create a many -> many relationship if you want to use
multiple categories? 

Table: auction_item
Table: auction_category
Table: item_category

You only have to use 2 joins here, one join for getting category data,
and one for getting category relations.

SELECT DISTINCT AI.Label, AC.Label AS categoryLabel
FROM Items AI
JOIN ItemCategory IC ON (IC.ItemID = AI.ItemID)
JOIN Categories AC ON (AC.CategoryID = IC.CategoryID)
