Shopkeepers are traditionally difficult to steal directly from - a whole
different set of skills are used to liberate items from shops, and
shoplifting is how you do it.  You'll usually be a lot more successful
trying to shoplift items than stealing them, or mugging a shopkeeper
for the loot in his cash register.

Additionally, shoplifting is usually considered a petty, non-violent
crime, meaning the risks of getting caught are much lower than regular
steal.  Charisma can also help you talk your way out of getting caught.

Note that large items are substantially more difficult to shoplift
than smaller ones.
