I recently bought a bass from Wunjo and had the best buying experience I've ever had. The guys were helpful and 'appropriately attentive' when I first visited; did me a great deal when I called to order a similar model to one I tried (offering alternatives on loan when the order time was longer than expected too - I didn't need to take up the offer, but appreciated what is surely beyond the call of duty) and specific delivery requirements were no trouble.
After disappointing shenanigans with various shops and online retailers in recent years, this was a breath of fresh air - I felt looked after by real people, who cared about their customers. I will go out of my way (I live in Manchester) to give them my custom again in the future. All in all, a confidence-restoring experience with a real music shop.
Cheers Wunjo!
