1 pack shy ??

Has anyone else opened up a series 4 Megabox only to find 7 packs and not 8 …happened to me tonight .. was shipped from GameStop I opened it up removed the security wrap and it was fully sealed .. also bought some series 4 collectors boxes last week and one box had the same 2 exact packs inside it …just wondering if this is a one off or has anyone else had this issue…I sent Cardsmiths an email hoping they can make it right seeing how expensive these cards are getting..to not get what you paid for is kinda a bummer
