I found related info from Anya Hindmarch's webpage:
Why is this new bag a different price to the original brown bag?
We have been overwhelmed by the world’s response to this project and inundated with requests to take this bag available to a wider international audience. The UK bag was priced at £5. This price meant that Anya Hindmarch and all launch partners have not been covering their costs. Despite this, we were all prepared to do it as we felt that we were doing ‘our bit’ to help to raise awareness of reusable shopping bags.
However, in order to launch the bag more widely & internationally, we had to make it cover it’s costs & ensure that no party loses money. The price for the next launches therefore, will be £7.50 (or the local equivalent).
We hope that you agree that this remains an amazing price for this bag. We also hope that the international launches will spark the same awareness and debate that we have provoked in the UK and encourage people to reuse, reduce and recycle!
How can I keep my bag clean?
Please brush your bag gently with a soft brush to remove everyday dust. Some people have hand washed their bags and this does seem to work but please do so with caution. We would advise spot cleaning with warm water and a gentle soap.
What do we think about the bags re-selling on ebay for inflated prices?
At first we were upset when the bags appeared on e-bay but then we realised that this is to be expected when there is so little stock and so much demand and this has led to creating more awareness which was the purpose of this project. Unfortunately we have no control over bags appearing on eBay. Please note that this bag is not a charity project so charities are not losing out.
