Specials not honoured at Burgundy Estate saying they are ONLY online - Other Branches do !

Very annoyed at Burgundy Estate branch. Wanted to buy a Platinum Rechargeable Milk Frother, but with the 2 mixer attachments on special for R99.99 (usually R129.99) Canal Walk branch only had the 1 mixer attachment on special for R79.99 (usually R99.99), and no stock of the 2 mixer attachments version. Went to Burgundy Estate which had stock of the 2 mixer attachment version, but would not honour special price advertised at R99.99. They also had stock of the 1 mixer attachment, but was also not being honoured at the special price of R79.99. According to Shaiera, this is ONLY an online special, despite Canal Walk having the instore special price too. Went to N1 City, and they were exactly the same as Canal Walk - special prices were honoured, but again no stock of the 2 mixer attachment version, only the 1 mixer attachment. So what is it? It would seem to be an online and instore special. Never seen Checkers advertise online specials only, and the advert does not say 'Only Online'! Somebody needs to advise Burgundy Estate that there is something wrong with their system. Look forward to hearing from you before the special ends on the 7th June. Thank you
