Transcend 256GB JetDrive Lite 360 Storage Expansion Card for 15-Inch MacBook Pro with Retina Display (TS256GJDL360) https://www.amazon.com/dp/B00WGARJGU/
Amazon had it for $ 169. Probably getting rid of these as new macbooks don’t have slots.
Still available to order says in stock 2/26.
Got this for $ 135 which I thought was a great deal at the time.
