While I understand you are probably exaggerating a mite...why buy tea not on special for points worth less that waiting to buy on special?
I have 5 cards...so bought one lot of discontinued Peppermint Tea which was going at a good discount as my daughters like it, but beyond that I looked at the prices and thought no... I can get more value by buying when on sale by saving the cash up front.. Ditto for the coffee.
Now I regard myself as an avid Points Runner, but I only grab points when it is the best option to do so and don't really understand the logic is stocking up on items at full price to secure points that don't offset the premium.
Now having said that the Everyday scheme has been great for me and I would estimate that it has allowed me to average over 2 points per $ spent at Safeways/Woolworths mainly on items bought on sale.
For a little bit yet those 2+ points to QFF are being augmented by 6.5 points to Krisflyer. After that it will be own to 4.5.
So say 2 x 2 (maybe 4) cents + 6.5 x 6 cents = 43 cent in the $ discount for buying selectively at Safeways.
