Wonky or not, that doesn't look like a lot for your money. Have you estimated what it would have cost if you'd bought the items separately?
But yes food waste is shocking, at least some of it is being sold, a lot of stuff that won't fetch a worthwhile price never leaves the farm. It's somewhat hypocritical that supermarkets are cashing in on these rejects, considering it was mainly them that set the standards. I try and avoid them, I either buy fruit and veg from a farm shop or the market. If I want to save money and am not feeling fussy, the market at 4pm on a Saturday is the place, a fiver will get me as much as I can carry and no plastic wrapping.
