Hello! Looks like you just joined iFixit Pro! Welcome! We offer multiple quality levels for screens. I’m not sure exactly what quality level you’re looking at but you should look at this one specifically: https://www.ifixit.com/Store/iPhone/iPhone-8-LCD-and-Digitizer/IF371-000?o=1
Premium - All of these screens are hand tested in the USA and conform to very rigorous standards for color, brightness, and are inspected to eliminate cosmetic issues.
A-Grade - These are tested in China and conform to specific standard but are not as good as the Premium grade.
Please [http://pro@ifixit.com|contact the iFixit Pro team directly] to discuss your discount level further which is based on purchase volume.
