These codes are generated and checked prior to being sent, as with every other current Netflix seller. I have a private code algorithm specific to the $200 denomination that is sold through Amazon, and therefore I am able to generate these in mass and check them. I will be selling them with a minimum purchase of ten at 5% each for bulk resellers or netflix fanatics.
