Okay, so I've looked over the boards for a while now, checked the website and still couldn't find my answer. How man OC does $1 get you? Is it more along the lines of $10=100 OC? Sorry if this has been discussed, but I definitely didn't see it anywhere.

Yeah, it's more along the lines of $10=100 coins, basically everything is Japanese-style overpriced, at least on the jp version, maybe the prices will be better here but I highly doubt they'll change the prices.

The Jp store ranges from 10-300 oc for their stuff (higher priced stuff being more packs with multiple items) while their gacha is 50 to x1 spin and 200 to x5 spin, again prices may change for en version, but I wouldn't place hopes too high. (though they have been pretty surprising with all the stuff they've done for this game.)
