FIFA 21 (Standard Edition) for PlayStation reduced by 79% to $20.98 via the PlayStation Store.
Was cheaper ~3 weeks ago when I bought mine - https://www.ozbargain.com.au/node/635684
I'd say wait - it will only go cheaper.
Won't wish this game to my worst enemy
They usually release the new installment late Sep so would definitely say will be half the price in a month or 2 especially if you're wanting the physical version.
