I've never had a issue either and I use them all the time. The Walsall store is practically my second home.
As im always repairing bikes for family/friends im always in there buying tyres, tubes, chains, cassettes etc,never had a issue with click and collect apart from when they didn't have a cassette lock ring tool that I needed but the bike hut guy just gave me one out of their own tool kit. Ive even turned up 5 mins after reserving items and it says itll be a hour before they are ready and staff have been great. When I do a bulk buy too (usually when im building a bike from scratch) the manager will give me a small discount to say thanks.
Though I have to say the store I used to work for (Cannock) was absolutely useless.
