Which Steam store is the cheapest that is ROW?

There aren't any really good places. Most likely you'll just have to resign yourself to the fate of buying games for the prices that the Steam Store sets. Or hoping for the games to be bundled.

Good question... I have really lost track of all this geolocking bullshit. Maybe someone can shed some light on the situation.
As far as I know right now, everything is region locked (except US and EU1?). And EU1 is never cheaper.

Keys however are not region locked. So nuuveem.br seems like the best option for everyone around the glove right now. Or the somewhat shady keystore like g2a and pinguin or what it is called, which apparently are somewhat save to buy from if the shop is actually offering these keys rather than someone else on their marketplaces.

Humble store has most games and they are region free (from my understanding of things). Also fairly cheap and supports charity.

i think he's asking for different Steam stores (Canada,Russia,etc.)
and right now the cheapest (for most games at least ) is the Canadian store,most games are around 10 to 20% cheaper compared to the US store(and up to 40% compared to EUR stores) .
checkout this website:
steamdb.info
search a game and it tells you the price of that game in every different store........

Well Im from canada and sometimes the triple A games are $10 more in cad :/

Canada for sure. Many games on the store are priced $USD=$CAD (so a $40USD game is $40CAD) but CAD is worth about 20% less than USD.

That game for $40CAD costs about $32USD

Japan, as far as I know

Not sure if they also have ROW copies, but Japan sometimes have cheap prices.
On some games we have cheaper prices in China as well and most games are ROW.

Publishers set the prices, so it depends on the publisher.

With default suggested pricing it's usually a toss-up between Japan, Canada, and Norway.
