You asked: Can you clarify the difference between up-, cross- and down-selling with an example?

Our answer:

The idea of up-selling is to sell more of a given product, usually at the time of purchase.  An example of this is if you order a lager beer (e.g., Stella Artois) and the waiter recommends an upscale, more expensive beer instead (e.g., a Trappist beer such as Westmalle). Cross-selling aims at selling an additional product or service. For example, the waiter might also recommend some abbey cheese as it pairs well with a Westmalle.  Finally, down selling means selling less of a product or service in order to maintain a sustainable, long lasting customer relationship. For example, if you had too many beers and order yet another one, the waiter might discourage you from doing so and recommend water instead.
