Just how much is a 20Kg bag of wild bird feed/food these days? I'm estimating that we use about 1Kg a day, pretty much all year round. Wild bird food prices are wild, wild birds are hungry. I think I got a good deal recently at a nearby garden supplier - £18 for 20Kg. That's 90p a Kilo.
I also enjoyed the strangely remote style of the place, I was met only by a white and ginger cat and made the transaction on the phone and picked up the sack of feed from a bin as if it was some kind of contraband. No physical human contact at all. A business model built on mystery. Other suppliers are available, or so I understand.
This is a really dull posting but dammit I'm quite proud of my 20Kg bag, even though it's now been decanted into smaller, more handy containers. How long will it actually last then?
