Wasteful Packaging

I’m curious what everyones experience with “theft prevention” is… Based on factual numbers - is it a real issue or an armchair-quaterback one?

To clarify - does so much product get stolen that it makes it worthwhile with the added product cost? (an extra $1 on shipping and packaging = an extra $5 to the customer at retail).

In my experience someone always brings up theft protection when we are discussing packing design. But if you show them solutions that make it easier to understand product features and reduce product cost, but sacrifice the risk of theft - the sales person to bring it up still prefers the former in the end.
