Screen replacement

In the USA it will be $149. If you use a third party repairer you will not get an OEM factory new display as those are only made available to Apple and Apple Authorized repair centers. Apple does not sell parts to anyone else.

All Apple parts and labor are warrantied for 90 days as well.

Somewhere from $100-$200 USD.

Definitely recommend going to 3rd party repair shop as it will be 40-50% cheaper to get iPhone 7 screen replacement

Apple doesn’t sell parts.

so you get a cheap knockoff that isn’t up to standards.

That’s why you pay less.
