-- Basically, if they purchased BEFORE the mistake was found, they get the originally advertised, incorrect pricing as an adjustment on their purchase.
-- However, any customer purchasing AFTER the apology is posted, have full notification that the price was an error, and can now see the correct pricing, and have no entitlement to the mistaken price.
THAT I have no problem with! If I bought anything after the price was changed or any notification was posted, then I will just have to suck it up (aka "be reasonable").
But if I bought it before the correct price was displayed, then I'd stand firm and let the store take that extra cost.
HOWEVER...that's not how Riot Games operate.
Two things:
Vel'Koz release: release skin: Battlecast Vel'Koz. Skin cost: 975 RP (was back when they were still doing promotional sales on 1350 skins). Price in the store on release (when I buy it): 1350 RP. Price in the store less than 1 hour after I buy it: 975 RP.
_They refused to even _acknowledge a 1350 RP skin would be getting a promotional sale.

Riot support: "so solly, it be plicing ellol mistake but you no can has monies back"
Was pretty much what they said as far as I'm concerned.
Second time:
PROJECT: Alpha bundle (Yi, Zed, Fiora, Lucian and Leona). Yasuo was also on sale separately (675 RP), but as I figured it couldn't be cheaper than 50% off in the bundle (though I couldn't figure out what was wrong with the bundle cost), I bought PROJECT: Yasuo first, and then went on to the bundle.
...And after buying PROJECT: Yasuo, I see why my numbers didn't add up. It WAS 50% off 50% in the bundle. So I contact Support again. And guess what? Nope, while they admitted their mistake again, I didn't get a single RP back.

On the latter case:
My ticket (excerpt):
There seems to have been an issue with the cost of the PROJECT bundle - even after doing some math before making the purchase, I didn't understand the 7222 RP pricetag.
1820 RP for PROJECT Yi
1350 RP each for Fiora, Zed, Lucian and Leona, totalling 7220 RP
1 RP each for the ward skin and icon (2 RP)
All in, 7222 RP.
However, the issue is PROJECT: Yasuo. The bundle was 7559 RP before I unlocked that skin separately, and it was only after I paid the 675 RP for PROJECT Yasuo + the 7222 RP for the bundle that I understood PROJECT: Yasuo had to be priced at only ~377 RP in the bundle, a fact that I was unable to find mentioned anywhere.
Reply (excerpt):
We're aware of a visual error that displayed the price difference in the bundle incorrectly.
TL;DR:
Even if I bought the bundle for the 1837 RP, took the screenshot from the news page where it said it would be 1270 RP (before it was changed), I GUARANTEE you I wouldn't have been getting anything back!
