Discerning Amiibo hunters will know that getting in pre-orders has been about the only way to secure a beloved character. In the UK, the first place listing the likes of Zero Suit Samus and the Inklings is high street retailer GAME.
You can either order online or pop to a local store and place a £5 reservation. Given that each shop has its own stock and online pre-orders are likely to go fast, the latter might be your best bet.
The less than reputable looking (but apparently safe) Shop.to also have a range of Amiibos on pre-order, including many that are otherwise impossible to track down.
Failing that, the likes of Amazon, Argos, Grainger and Gamestop UK shouldn't be too far behind. We'll do our best to let you know.
