This tool is for anyone comparing prices across different pack sizes, stores, or promotions – especially when mental math stops being reliable. Or your brain… whichever.<\/p>\n

In this scenario, which was one of the first times I wished an app\/site like this existed, I was doing my grocery shopping for my 3-in-1 coffee. Birdie (Robusta) Red to be specific. As can be seen from the screenshot (hopefully):<\/p>\n
- \n
- Tops – Sells a pack of 27 satchets for THB 105<\/li>\n
- Lotus – Sells a pack of 40 satchets for THB 145<\/li>\n
- Makro – Sells a pack of 60 satchets for THB 196<\/li>\n<\/ul>\n
The Live Preview window at the bottom then spits out the key information that a user might be interested in – Makro is the cheapest, with each satchet bought there averaging out to cost THB 3.27 as compared to THB 3.63 at Lotus, and 3.89 at Tops.<\/p>\n
Of course, economy of scale is a simple way to look at these things, and a larger pack should in theory always be cheaper…\u00a0BUT<\/strong>, this is not always the case. This scenario was only an example anyway, and promotions, and especially those “online” like via Lazada\/Shopee can really make the math rather interesting (once you take into account shipping costs as well where necessary).<\/p>\n
For the most part, the Live Preview section\u00a0should<\/em> be enough for most of us to make an informed decision. If you’re looking for more information, or if you prefer neater tables, you can click\u00a0Compare<\/strong>, and we’ll be whisked off to the next page.<\/p>\n
Comparison Results<\/h1>\n
Here, we’re treated to a marginally nicer looking table with like 1 extra column showing efficiency % versus the worst performer. In hindsight, I’m not even sure why I created a new page for this single extra stat… but I personally like it… and that’s good enough for me.<\/p>\n
