obviously food and medicine are likely to be the most immediate concerns, but energy, communications, satnav, air travel, VAT etc etc will all impact hugely on us
for example, VAT bills will need to be paid 3 months early.

If you plan to sell £100 of wood, and pay the VAT after you have sold it, and now have to pay the VAT BEFORE you sell it, you are not going to buy £100 of wood to sell, are you.
You are going to spend that £100 on £80 of wood to sell, and the VAT on that.
So basically, a 20% drop in the amount of wood on the market
