> Store's own brand is like 20-30% cheaper across the board. How is this even possible?

No need for marketing costs. Also companies compete for shelf space (sometimes they will have to pay to have their products placed in a favorable spot). Also they buy BULK. When (e.g. Tesco) buys bread they issue the recipe they want and they guarantee LARGE volumes.

Regarding the comparisons, in EU they got labels that give you cost per 100ml or 100gr or per item.

Also a quality of such cheaper own brands is lower. Tesco Value is garbage, but they have premium brands which are not cheaper than popular external brands and with decent quality.

And I have a feeling they intentionally increase price of other brands to force people to buy store's brands.

They are not always lower, in my experience only some store brands are (on average) of lower quality.

And many individual products are still good enough.

The unit issue is in the EU. You can't sell everything by 100 g or 100 mL, so it is ultimately up to the seller. Another example of it is toilet paper, sometimes given in money/square, sometimes given in money/length.
