Do not pay more than £25 for these bags. They only cost this amount in regular shops i.e. Debenhams, John Lewis. They are also available at this price via internet sites (regular small outlets) and with no postage to pay!
In general be informed of prices before you start bidding else your 'bargain' may turn out to be at an inflated price.
