It seems Coles has been following the blogs a bit too closely, or they've finally employed someone who is switched on.
Since October there appears to have been several significant changes to the FB algorithms for creating the offers - changes that could even be described as 'enhancements'.
The last time changes appeared to have been made was around mid 2019 or so - which caught out quite a few players initially. See this thread back then.
These latest changes are far more focussed (it appears from my analysis).
Prompted by FB's sudden 'loss of love' for our family's individual accounts late last year - I dug into the old receipts sorted into each person's account (yes I keep them for a while as I also like to track how the prices get changed frequently (up) with no fanfare but that's a different story.
A number of things caught my eye after slicing & dicing the receipts.
- Be careful how you pay for purchases if say spending $3X with $X across 3 separate accounts - seems to have had a nasty sting added here for one type of payment method. Think about it & work it out without naming it on any blog otherwise the work around will soon fail. After I noticed this - we changed our approach & within 2 weeks we started getting decent offers across all accounts again after nearly 4 months of famine.
- Buying a relatively large value item as a one-off (say $15 to $40 price) other than fresh meat - stays on your 'spending profile' for offers for up to 13 weeks it seems & influences what offers you receive. This was not the case previously (compared earlier one-off purchase examples & no ill-effects then). So perhaps, unless really desparate - forgo the 15 to 40 points for that item & buy-it off-FB card by itself.
- Having a delay (same day but some minutes) no longer serves any purpose if you pay exactly the same way as you did for the slightly earlier transaction even if it is anothe FB a/c.
- C & WW's approach diverged massively starting in 2019 and perhaps someone from WW is now working at C's FB.
