I just received another email saying JayJays have a 30% off store-wide sale tomorrow (24th November). Includes web store and retail stores.
The deal doesn't seem to appear on the link yet, but it should activate on 24th November.
Should work in-store or online.
EDIT: Appears to only include 30% off full-priced items, not sale items unlike the sale last week.
I think its only on full priced items.
