Think I'm going insane here. For 2+ years my wife and I have bought bags of protein powder, replenishing when needed. Currently there is a 10%-off Easter discount from the manufacturer, stacked on top of a bulk discount. We disagree on whether buying in bulk is financially sound.
My argument is that we save more by buying a whole bulk at once, since this is a regular consumable we've used for years and know we will continue to use.
Her argument is that we'll actually be spending more money since the cost is all at once, and that we can't afford it because she has bills to pay for an upcoming holiday of hers.
We have ample savings and earn decently. Our interest is only something like 3%. You get a free shaker bottle when you spend over $150.
What am I missing?
Edit:
We normally buy 1KG at a time at $60
Bulk + discount works out to 1KG at $48
Editwo:
My wife came around and agreed that it makes sense to get the protein now in bulk. This was how I first jokingly brought up the topic, so understandably it may have sounded like a crazed "BUY BITCOIN": https://i.imgur.com/nYdO1FY.png
I'm getting 5 x bulk bags, because it's a once-a-year discount for a brand we've used for 2 years. After that, I'll take on board advice in this thread to try Bulk Nutrition and Optimum Nutrition. If that turns out well, I'll switch to one of those brands and save $$$ like a happy OzBargainer! Thanks again all.
She's right in saying it's better to spend money gradually. It's worth more to have now than it is to have later.
It would have to come down to how much of a discount it is.
I noticed for Bulk Nutrients there's hardly a discount when buying in bulk so I just order a kilogram at a time.
Will the 10% off offer happen again in the next few months?
