>>9374071I buy straight from Taobao. Pricey because you need a forwarding service, but I get it really fast after release.
Other than that, all the three methods you mentioned are reliable enough. Just research fair prices and don't overpay from scalpers, and you'll be fine. The only Beastbox knockoffs in existence are of Dio, and they generally look so shitty you'll instantly be able to tell.
