How often do Debenhams/John Lewis do their discount days?

minerva_windsong

I have a couple of make-up bits I'd like to get for my wedding but am holding out for a John Lewis/Debenhams discount day so I can save a bit of money. Does anyone know how often these come round? The wedding is in early November so ideally I'm hoping there'll be something before then - I have a vague memory last year they had one in late September.


Also - when they have these days, do John Lewis do it across all their brands or just the ones Debenhams stocks too? Does it include brands Debenhams sells online but not in stores?


Thanks in advance for your help!
