Based on some sites' feedback collected from their clients, we have renamed the INCLUDE green button to Add to Cart.
Our reasoning for for making the change is simple. Unlike in 2003 when first coded, the term Add to Cart has become a standard metaphor across the web. Correcting our button name might help some first time Users. Like chicken soup it is not likely to hurt them.
Note: The button remains green and the location did not change, so this should have little if any impact on current Users. We know they don’t read anyway.
