Geek Squad, We were flying under the radar upgrading Macbook RAM, until one day we became officially Apple Authorized to fix iPhones, which means we were no longer allowed to upgrade Macbook RAM since the Macbooks were older and considered "obsolete" by apple, meaning we were unable to repair or upgrade the hardware the customer paid for, simply because apple said it was "too old". it was at this point in my customer interaction, that we recommend a repair shop down the road that isn't held at gunpoint by apple ;)
I worked at a 3rd party Apple retailer (they had a legacy contract from the 90s that only expired about 5-10 years ago) and they bought the cheapest RAM they could find to upgrade the Macs. They made hand over fist on RAM upgrades and still came in under what Apple charged for the same upgrade.
