Ymmv, for me i havent flown Virgin regularly for over a decade (since i last had a job where Virgin was preffered carrier for business trips to Albury and Port Macquarie). I have no status with them and as they are not part of an international alliance, im better flying with One World carriers where i have lounge access etc if travelling 9n my own dime.
The Virgin points i have are from Delta flights years ago, ive been transferring minimum FB points once a year to keep active, but have not been able to redeem for anything useful. So i have points sitting in FB unused in hope they eventually offer transfer to Qantas which is more valuable to me personally when agregated with other QFF points earners.
I shop at Woolworths maybe twice a year, as none within walking distance of where i live. I shop at Coles or IGA so would love extra QFF pointsfrom Flybuys.
