These are advertised in the 25% event brochure and will be available from WEDNESDAY 19th Nov - 8am, when the Debenhams main sale starts. Im not sure about online availability so i listed this as instore only.
Most people will know these as "Hot Offers" but Debenhams are no longer calling them that anymore. But anyway since these are a BOGOF deal they are excluded from a percentage discount and will be full price.
Different stores will vary in stock, the £14 ones you can see in the link but Middlesbrough store sells a £35 pound set of 2, so your getting 4 for £8.75 each.
First post so ive tried to give as much info as possible, if ive made any mistakes please pm me on how to rectify them.
