What is chroma key? It is a technique for mixing two images or frames together in which a color (or a small color range) from one image is removed (or made transparent), revealing another image behind it.

The technique is also called color keying, colour separation overlay, greenscreen and bluescreen.

There’s just something about getting free shipping that feels right — which could explain why some people get upset when they feel the free shipping is really a bait and switch offer. This points at an issue that isn’t really covered in the original article. One of the reasons why people like free shipping so much is that they don’t feel tricked at the end of a purchase. Too often, online retailers hide excessive shipping and handling fees and only make them show up at the end. This makes people feel tricked…”
