I agree with the parity bit, I hope the pound strengthens against the dollar only because I want to take my mum shopping to New York, as for a £2 spike, don't we all.
Not sure which Aldi/ Lidl you use but I see no signs of superior management skills in the branches I've visited. I can never get help so stopped trying. Coupled with long queues at the checkout and I mean long, lack of parking if any makes for shopping a unpleasant experience. I do like their French week only because I'm a sucker for escargot. Unfortunately I've now found them elsewhere so it's good-bye Lidl/Aldi. Good luck and DYOR
