cheapesr place to get my screean repaired

On a Mac that is less that three years old, the Apple Store is about the only place that can get the exact parts required.

In the US, be sure to enquire about "depot repair" which you should expect to take just over a week, including transit time (despite their protestations that it takes less) and can cost far less.

If your MacBook is OVER three years old, there will be "computer junkyard" screen assemblies available, which have been removed from similar Macs that died from other causes. These can be substituted for your screen assembly quickly and comparatively cheaply, often with a very modest warranty.

"Place" and other "where can I get..." questions are much more easily handled if we know roughly where you are. These are international forums so we get inquiries from all over the world. It doesn't help you if we recommend a vendor who does not ship to your location.

The Apple Store.
