Not directly Avios related, but had a mail today to say the Caffè Nero partnership is ending - no more exchanging Nectar points for free coffees after the 18th August. Disaster - that was by far my best redemption usage, and my benchmark value for Avios if I converted to nectar (i.e. about 1.5p)
I'm going to lay in a huge stock of coffee vouchers before the deadline, they will still be valid for a year.
