The A73 is a really odd model.
If you look at the SD778 SoC, you can get the Galaxy A52s for a lot less.
If you look at the camera features, the A72 has telephoto lens, which Samsung weirdly dropped on the A73 (and they use the useless macro and depth sensor instead).
If you look at the price premium, you can probably get the S21 FE for almost around that price point or just a bit more, which will give you actual flagship material like aluminum frame and telephoto lens (the A73 has plastic frame).
To make it worse, unlike the cheaper A53, the A73 doesn't get monthly security patches. It only gets quarter patches like the cheaper Galaxy phones.
Imo if you are looking for a phone in that price segment, I would try looking for a deal on the S21 FE instead. Or you can save money by just getting the A52s instead.
