We have a nearly brand new Bugaboo pram transport bag. Bought it after our pram was damaged on a long haul flight. It's really handy, light but sturdy and you can pack lots of stuff in and around it. Highly recommend if you need to go on a trip. We have a Chameleon - think it works with Frog too. (and possibly other types of Bugaboo)
£50. We live just off Clapham Common. Call me on 07880630530 or PM me.
