Hi friends, I am about to provide you with information that may well put your family in the poor house.
Kmart seems to be having a big amiibo sale.
It's necessarily advertised anywhere and it appears to be in-store only, but nationwide it appears as though Kmart is selling select amiibo for $4.
According to OzBargain, the following amiibo were being sold at $4 while stocks last:
Bowser Jnr Captain Falcon Dark Pit Ganondorf Greninja Inkling Boy (Splatoon) Inkling Girl (Splatoon) Jigglypuff King Dedede Kirby Luigi (Super Smash Bros) Mii Brawler Mii Gunner Mii Sword Fighter Olimar R.O.B. Zelda
Vooks also has the lowdown on the sale. Apparently some people have picked up a Yarn Yoshi (undoubtedly one of the coolest amiibo) for $6.
This strikes me as a proper, old-fashioned clearance sale -- meaning that if you want to get some of these amiibo you'd be advised to get your arse to Kmart ASAP.
