Give us 1 minute to undo a purchase ...

I just bought a runepage with IP when i couldve spent RP to buy it and use the IP i spent on runes instead FML But then i thought, hey you know what, thats a good idea!

i think 1 minute to undo a purchase is more than reasonable because you can't even use an item within a minute, like skins or champions. It should just exist for when people buy something by mistake :P
