For example, if you sell them a widget and at checkout you ask if they would like to add a widget binder to their cart, that's a cross-sell.
If at checkout, they buy a widget and you see that many people who by widgets also buy sprockets, you might offer people who buy widgets the opportunity to buy sprockets at that time too, that's an upsell.
You generally won't sell fewer cookies, just an additional kick in revenue from the milk.
You could also sell Coke on a page about Pepsi and give the user a choice. Generally in this case you have to be careful that Pepsi doesn't steal your Coke revenue if Pepsi pays out less.
some people also call it screw-selling. it's when a customer gets screwed on big money.
problem on the web is that your web page is doing selling, and all a sucker needs is a click of a mouse to shut your sales pitch.
...you can get it from my rant I don't like salesman too much...
"Click here if you are prepared to spend more money on some features and benefits that you don't really need, but may just inflate your ego and briefly, until u get your credit card statement, your satisfaction with the purchase" :)
Cross selling online is good business - e.g. you PPC for traffic for long haul flights, but the visitor wants a local flight. Much better to offer the lower margin item than just waste the visitor.
