The 2020 tour merchandise was recently added to the webshop items in BF's website.
There will presumably be good stocks of everything, as the tour never made it beyond the UK shows; last time I looked the price of the tour programme had been drastically reduced, for example.
Even more recently a range of coffee mugs featuring various Roxy & BF album cover art* was added for pre-order (from memory, I don't think absolutely
all of these were on sale during the tour), but these seem to have disappeared again! It's probably worth checking semi-regularly for their reappearance...
(*I think the range included all the Roxy studio albums and the first five BF ones; they were £7 each.)The link to the webshop is
