While researching on ways to improve the online shopping experience, I came across the following article:

http://psychology.wichita.edu/surl/usabilitynews/92/shoppingcart.html

The article returns to review findings they arrived at in 2002.

One thing I noticed was the first recommendation:
Calling a Shopping Cart anything but a Shopping Cart.

The article writers do clarify in the second paragraph that it is ok to call a shopping cart by another name as long as customers are familiar with the term. eg. shopping trolley is a more suitable alternative name in the U.K.

The seventh recommendation:
Make it easy to remove items from the shopping cart.
