you can get it for free if you so desire.

um GMG with coupon? wait for a sale? i dont get how 10% is that big of a deal, it's not like it's 50%... why do you want an old game so bad?

GMG with coupon is the cheapest atm. You'll have to wit till the winter sale if you want it cheaper than that since Squaresoft games rarely go on sale.

Buy it's android version when next new year coming. (high probability will be 50% off)

I got it for 1,5€ :)

On a garage sale.

for PS1

I would recommend waiting to get that one, it has some nasty bugs in it. For an example, I've had issues with it picking the wrong menu command (and no, I don't just accidentally hit up or down, it jumps to a specific spot on the command list quite far down).
