I ordered my key from Online-Trends at 11:20 yesterday (UK time), and received my key at 18:45. So it took 7 hours 25 minutes to get a key, but I did get one same-day.
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
