I ordered my R4 from mod-chip.com. Sent on 27th Dec. and arrived here in UK on 30th on the standard delivery option.
Only problem is that I'm still waiting for the microSD I ordered at the same time from Ebuyer to arrive -- due tomorrow 3rd Jan.
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
