Keep in mind that we get a lot of posts here of a questionable nature, so when we see a question about trying to bypass some kind of security feature and the mention of getting something "off a pallet," it raises red flags. Apologies if wrong assumptions were made, but we as a forum have strict guidelines against discussions about bypassing security features, so the more clearly a person states the case, the better.
I've never heard of this store practice -- is this what you're referring to?
