Watch Out When Buying Crypto From Wallet apps!

I recently discovered that you can buy crypto from some wallet apps, without ID verification, but watch out. I for example BRD offered some reasonable fees, but their price was around 2,400$ above the normal. I do not know if this is the case for some other wallets, but this is only based on my own experience of a somewhat popular wallet app with 4.5 star in reviews.
