Recently posters have been experiencing problems with using vouchers printed from emails etc. and retailers refusing to accept them.
But having read the latest free Aqua Mist voucher you can certainly understand the retailers reluctance to accept them. At the drop of a hat the promoter can refuse to honour it if it believes that the voucher has been sold, traded, copied or duplicated. Well why should a busy trader have to take time out to decide whether a voucher has been copied etc.
I will attempt to use my voucher at Asda.
