Now that would be interesting if they have adopted the approach that CCs used to use to convert (brainwash?) clearers to revolvers.
In this case they're using the 'addiction' to points to increase their share of wallet, and most likely (for the non-AFF world) lead to much greater food wastage.
Prior to the change in legislation about having to opt-in for credit limit increase offers - CC companies would track the seasonality of your purchases and then offer you credit limit increases (by what the pyschs said were not 'bell-ringing' amounts) a few weeks before you typically increased your spending.
So if you normally planned & bought your holiday airfares/accom etc in April then you'd get limit offers in mid to late March.
The trick (devious, twisted, evil...) was to apply the 'death of a thousand cuts' to users habits. Or the 'boiling frog' approach - encourage you to spend ever increasing amounts until you reach the limit level where you spend more than you can pay in full by the due date. Some of the less caring issuers would aim for two or three limit increases past this point so that you're really hooked.
Does anybody else wonder if the new gen operations like AfterPay are a variation on this theme?
