...or discounts. These are perks and benefits offered by Companies to shareholders' which usually take the form of discounts or money off vouchers when you buy from them or use their services - hence a when you spend you get a saving or "spaving". For example Marston's (MARS) which I mentioned yesterday offers shareholders' with just 84 shares what they call a privilege card which entitles you to 20% off food and / or hotel accommodation at participating properties. Greene King and Restaurant Group also offer 20% to 25% off food and drink via vouchers.
While I wouldn't recommend buying shares just for the perks or discounts they can in some cases be a nice bonus. Having said that on one occasion in the early 1990's I did do that with a stock that was then called Burton Group which owned and has since morphed into Debenhams. At the time I seem to remember that they required you to own something like 500 shares which at the time cost about £1500 at a price of 300 pence. I bought them though after they had collapsed to 30 pence and had a rescue rights issue after they had over expanded under their "energetic" CEO Sir Ralph Halpern. Thus I was able to secure a shareholder discount card for £150 which has given me 10 to 20% discount in their stores ever since. Thus I have "spaved" many times that amount and got some great bargains in their frequent half price sales and blue cross days back then. In addition I have had dividends along the way and even though my shares were bought out at a profit by a VC firm I still get the discount to this day.
However, be aware if you hold your shares in a nominee name you will not always get sent these offers automatically, so sometimes you have to get your provider to request them for you from the registrars. The best source for a full list of Shareholder perks and benefits is the following page on Hargreaves Lansdown's website. But as I say don't buy shares just for the perks but in some cases depending on your circumstances I guess it could make sense or if the minimum amount of shares is low enough.
