I, sad to say, have never been a fan of B&H. Maybe if I lived in New York and had access to one of their stores.
I have never had any joy with them. I would rather deal with Amazon, when it comes to electronics, any day of the week.
I have, alas, been suckered into previous trade-in SCAMS by B&H. They are not dealing in good faith. From what I can see there are just trying to get your contact information and then say that they are not interested in your trade-in.
So, I am not going to bother, though I do have a rather nice Sony a7 II to trade-in. Instead, I am going to sell it myself. I hate being scammed.
