Thanks for the input all.
It’s a difficult one. Saying that, and thinking about it, it’s probably going to be exactly the same for all of us – no matter what time of the year we order. Advance prices tend to be erratic what with Covid19 and the way the world is right now. Brexit may or may not be a factor – who knows!
I guess I’m going to have to go down the ‘Order now & re-order if the AP is lower’ route after all.
