Lower price Phones

[NexoFih]

Hello. I've been searching for a phone I want to buy, it is called Samsung Galaxy S23 Ultra. In my country, Romania, the lowest price (if you buy the phone from an official electronics store) is 1100$.

I searched that specific model on my local marketplace and a brand new full box phone can be bought with 900-1000$. The people sell sealed S23 ultra s at this price, which is fair enough. All good till now.

Today I found out a GSM shop in my area has new sealed phones and figured that a S23 ultra costs only 950$ (with invoice and warranty). The question is: how can they sell phones at such lower prices since the cheapest electronics store in my country sells the exact same phones with 1100$? I mean where did the GSM guys bought those phones from? Since they sell them with a difference of 150$ and still make profit from these sellings?
