Thought this may help a few people.
I popped into Toys R Us in Merryhill (West Mids) and asked if they had any bags for the Loola travel system. They had none on display but she said they had loads in stock (all colours). I also bought the Windoo cot for the Loola and it was £114 (also in Oxygen red). reduced from £169.
The web site appears to be constantly sold out.
Remember to ask, as all the Toys R Us seem to be clearing this stock ready for the updated version.
