Resealing damaged Products

The ***** for a sealed box and then sell it separately. I baught a few laptops from them cash about 3 weeks ago my wife told me the seal looks tampered with but i didn't make much of it. But forgot a Christmas present for my brother so I went online and got the exact same laptop for about 25% cheaper on takealot got the laptop about a week before Christmas and when we opened it, it had an extra memory card included which the box mentions on all the laptops Bytheway. So i went back to my Hifi corp box and looked through it again and again. When i finally noticed the seal looks totally different yet it's from the exact same manufacturer. Meaning they damage the seal take out all the small extras and sell them separately. They are a ******** organisation. First they over price a product secondly they remove small parts and ask you an additional fee for it( i do understand company markup but removing parts and markup must be somewhat *******) it's like buying a car and paying extra for the seats and steering wheel
