Grocery Shopping List Price Optimizer - The Power of the Price Awareness Across Different Stores
Baby Edition - A Few Examples On Diapers And Washing Detergent
The upgrade from being just a married couple to a family 7 months ago brought many challenges. One of them was also of a financial nature, having to provide the usual items for the baby. The monthly bills almost doubled, plus my sanity was under additional stress due to all the possible diaper prices, offers and almost half-a-dozen different package sizes for the same diaper brand, type and size. Not to mention that diapers are only a small part of everything when a baby is born.
One would say that that was one of the reasons I've decided to come up with Grocery Shopping List Price Optimizer. If you're a parent getting lost in all of that baby stuff and prices, the following information should definitely help you out.
Here are two success stories of mine when it comes to dealing with mandatory baby accessories.
1. Pampers - Baby Dry 👶
One of the well known new challenges of undergoing the new parenthood status is also changing the baby's diapers. There is no way around that. And there is a lot of changing. I give my sincere thanks to my wife for taking care of almost all diaper change sessions. The statistics are about 1 change per day for me, and 4-5 from her side per day.
But, I'm the one who is buying them, so that should narrow the gap a bit, right? 😊
Here is the current situation for somebody who wants to buy Pampers - Baby Dry (size 4), checking at preisrunter.at:

Wow, "just" 47 results found. Packs from 24, 25, 27, 30, 56, 62, 66, 72, 108, 180, 198, 204 ... and now, who would want to go through all of those calculations like every 1, 2, 3 weeks, trying to get the best deal? I tried, and got a few additional gray hairs.
But then, the Grocery Shopping List Price Optimizer came to the rescue.
Let's see how much one would pay for diapers, for 6 months (taking size 4 as a reference - 9-14kg baby), if one was going only to SPAR and blindly buying them there, not taking any regard to the price, and not wanting to go buy them every week.
Currently there is this SPAR offer for a 62-piece pack, which might last just a bit below 2 weeks.

So that is 0.29€ per diaper. The baby needs about 4 diaper changes per day (it varies between 3 and 5), so for 6 months that would add up to 720 diapers.
Buying 17.99€/62 pack -> 0.29€ per diaper * 720 -> 208.8€. That's for 6 months of diapers.
Now check how I'm doing it — brainless-mode — because Grocery Shopping List Price Optimizer is helping me out. This is my entry from the app.

To explain, a few months ago I've noticed that BIPA has quite regular discounts on those diapers. So when they occur, I stock up sufficiently. Now check the result.
Buying 13.32€/72 pack (discounted) -> 0.18€ per diaper * 720 -> 129.6€ for 6 months of diapers.
You already get the picture, but let's make a final comparison for 6 months of diapers we just did:
- just go and buy, no regard for the price approach: 208.8€
- with the help of the app: 129.6€
That is more than enough money for me and my wife to order a 4-person order (if we're super hungry) of a premium sushi home delivery 🍣, and we would still be left with about 10€.
2. Frosch Baby Waschmittel 🧺
While going past it in the SPAR 2 days ago, I noticed there was a new price in place. Currently sitting at 7.39€/1.5L.

Checking at heisse-preise.io, the price did increase from 6.99€ to 7.39€, so +0.4€ which is a 5.72% increase in price. I guess the increase in the gas prices lately has it's impact.

Good thing (for me) is, that per my entry in Grocery Shopping List Price Optimizer, it doesn't affect me, as I'm buying it on Amazon.de at the right moment.


At the start of June, there was a superb discount on that item when buying more.

You see that here? 3.99€ per 1.5L bottle. Now, let's compare that with SPAR's current 7.39€ for buying the same amount of bottles (10).
- SPAR: 73.90€
- Amazon.de (with help of the Grocery Shopping List Price Optimizer app): 39.90€
So, not only did I buy the item at a significantly reduced price, I'm also basically covered for at least 1 year by it, and I don't have to worry about it anymore. That should cover a regular 2-person premium sushi home delivery order for me and my wife 🍣.
Now that's the stuff, improving the state of my life, brain, and wallet. Well, and my wife's sushi-desire-meter, keeping it sufficiently low 😄.
