So bought a few items a few weeks ago at B&Q. Most were fine but I bought too much of the one item (kiln dried sand). Not a problem, will return the excess bags and get my money back. Except when I bought them I was asked 'do you want a receipt' and because I deeply care about my environmental footprint I said no. Now B&Q are saying without a receipt I cannot get a refund, only a credit note. So basically the B&Q policy is 'care about the environment and be disadvantaged compared to those who don't'
