Stocks with shareholders perks.

Usually, investors only consider a stock for the dividend and capital gain potential it might offer. However, there is a small group of stocks that not only provide all the traditional benefits of stock ownership, but also give shareholders other offers and freebies that can add up in a big way. 

If you take a cruise every year, buying some stock in your favorite cruise line could pay for itself many times over. Here are a few stocks that offer long-term upside potential as well as shareholder perks that are too good to pass up for some investors:

Carnival Corporation (CCL) offers investors who own at least 100 shares of stock a shipboard credit of up to $250, depending on the length of the cruise. 

Royal Caribbean Cruises Ltd. (RCL) also gives shareholders who own at least 100 shares a shipboard credit for up to $250. 

For people who frequently cruise, this could pay off quickly, and this perk makes sense for the cruise line to offer as well.
