Would this closing straight after Christmas of been planned ?
As they knew very well that loads of people would be buying there gift vouchers for Christmas presents
Absolutely yes, it would have been planned and arranged well before Christmas. A lot of ex national high street retailers have pulled the same stunt many times over the years. The vouchers just make anyone holding them an unsecured creditor, in other words, bottom of the pecking order with no chance at all of getting anything back.
