I saw a promotion which you can trade in a Samsung z flip 3 for 900$ instantly which you can use it to purchase a Samsung z flip 4 and they also offered free storage upgrade to 256GB with the same price of 128GB. On top of that, they even offered a free case cover and some streaming services for free up to 6 months. Unfortunately, after checking, I found out that this promotion is only offered in the US! I thought this offer would be available in any official stores across the world but why Samsung why? I went to check the Hungarian Samsung store and the price of the trade-in Z flip 3 is only 156000ft which is approximately only 400$! and there is no free cover case whatsoever. They claimed to also add 80000ft (200$) discount upon purchase but it does not even come close to the promotion available in the US. I am not talking about tax because obviously I gotta pay it but why are you giving different promotions to your customers?
This is written out of frustration after chatting with their online experts and checking by myself, if someone does know the additional information plz kindly help me out here.
