Casinos often give away so-called “logo items” — things like key chains, decks of cards, sport bottles, hats, and so on, marked with the casino's name and logo. These trinkets may be part of a welcome pack for new player's club members or hotel guests, or they may be part of a special promotion. For example, some casinos celebrate their anniversaries by offering free merchandise to, say, the first 200 people at the buffet that day.
Most casinos also have a player's club store or catalog where you can exchange your comp points for merchandise like jewelry, electronics, clothing, and luggage. Instead of price tags, the merchandise has tags that show how many points you need to “purchase” the item. Some players save up their comp points for this purpose, rather than using them for meals or something else. The casino host can tell you how the comp points system works at that particular casino.
When it comes to handing out comps, not all casino personnel are created equal. Typically, a dealer can't give out comps, but he or she reports to the floor person, who fills out the rating slip and can give out meal comps. The pit boss has authority to give out room and meal comps, and the shift supervisor or VIP host has the authority to give out any kind of comp.
