I have read that it is around twice a year. I just did the Father's Day promo. Apparently, there was a Mum's Day one too.
You were lucky to source $100 cards for the Father's Day one - scouring the nearest 7 stores repeatedly (3 in largest Coles store category) had zero. Asking for Store Mgr to 'discuss' lack of cards got no satisfaction as store reputedly cannot order them in but just gets sent what they receive (or don't as the 7 that had previously had them did not). Of those - 6 still have not had any come in since September as I have been waiting to obtain a supply for future (now eventuated offers). The 7th had a grand total of 12 or so cards and several hundred of the $50 ones. All 6 other stores had more than a hundred of the $50 ones as well (before, during and after the Father's Day offer).
This is at least the fourth outing this year for bonus points.
- Mother's Day - 1,000 points/$100 C MC gc or 500 points/$50, limit 10 C MC gcs per transaction
- Father's Day - 1,000 points/$100 C MC gc or 500 points/$50 (as above) DEBACLE with ZERO supply at 90+% of Coles stores mainland-wide = very unhappy families Australia-wide
- October (finishes today) - 2,000 points bonus - limit one card per FB household account.
- The two variations shown above - 1,000 points/$100 C MC gc or 500 points/$50 (but only covers $5 fee notionally on the $100 cards)
I suspect the 2,000 points offer was a 'veiled' apology for not having any in stock and still they don't.
