Was the box open? The C/Bs should have all been in the tripped position. They run through a magnet just prior to shipping which trips the magnetic trip.
Big box stores take returns and unless there is a defect according to the customer, put them right back into stock on the shelves.
Always check EVERYTHING that you buy from the big box for SKUs, bar codes, prices on the receipts (sometimes double of the shelf price), and obvious defects.
Don't worry though, they will take the CBs back (and unless you tell them about the defects, will put them right back on the shelf for the next unsuspecting customer)
