Not sure if/how such announcements are viewed here, so apologies if this proves to be a posting faux-pas!
Probably redundant anyway, as doubtless most RTMM'ers will be on their mailing list anyway, but just in case, ORBX are having a sale at the moment, 50% of a broad range of their stuff, including most if not all that fall within the RTMM area of interest.
Live now, lasts until 18th February 2019 at 01:00Z.
Now to decide if I want to PNW, or if I should grab Global Vector whilst its at 50% off...
