These speakers have been around £50 ever since the Rdio service stopped. However now the white one is down to £40.
Speaker has airplay and spotify connect. I have 3 of these in different parts of my home and they are really very good for the price. Sound is good enough to fill a decent sized room. You would obviously want something more powerful for a large party.
Standard delivery is £3 but you can collect for free at either of their two stores.
