If you can print a label, you can then book a collection on the RM site (at the moment you can only book a collection, not have a label brought to you). I have never used a QR code in my life as I don’t use apps or my phone for anything other than, well, a phone 😂 I drop my phone too much or end up squinting to read anything (despite wearing glasses) but mostly I struggle to use phones these days.
