Sold him a total of 183m RSGP in increments of 10m via PayPal gift method. I went first and he was very patient with my request for small increments and is one of the most trustworthy buyers I've had the fortune of trading with.
Vouch for H o l y One, sold him a $20 UGC (3 month membership) for 13M. I went first, he paid me immediately afterwards. Went very smoothly, no issues whatsoever.
