Just popped into B&Q (Guildford)
They are selling off their seed potatoes for £1 per bag, yes they have white roots growing out of them, but they have dot started to shrivel up so should still be good.
The non-Bargin... somebody pointed out that their MP compost was 3 for £10.
I had noticed the price had gone up, so it was music to my ears to hear they were repeating the same offer as last year, but when I looked today, I noticed the bags were now 60L rather than the 70L they were before, so quite a decrease. :(
