My Mac was in need of an upgrade. I watched YT and found some videos that explained how to upgrade my Mac and they recommended MacSales. MacSales website was very easy to use on what to order for the year and model of my Mac as opposed to other websites. I ordered four memory sticks and attempted to put them in. I found that two of them my Mac was having an issue with by not turning on the screen. I contacted customer service and they sent two new memory sticks out and they went in without an issue.
