Grapes for 10p, Strawberries 40p? Last time I went shopping a punnet of grapes was £2+ and im sure blackberries and blackcurrents are £2.50. Granted bananas are cheap at about 10p each
Depends where he shops I guess.
In a Supermarket, yes, you will be paying a lot, £2 at least for Grapes like you say.
However, if you go to a market or independent business, you can get them really cheap. We get a lot of fruit sellers around where I live who will sell you whole bowls of different types of fruit for a £1. The only downside is that its often more ripe than what you get in the supermarket, so you can't leave it for an entire week.
Coincidentally, Channel 4's Dispatches tonight reported on Supermarkets and how they overcharge us for fruit and veg, yet make a killing on it. It's not up on 4OD yet, otherwise I would have posted the link.
