Amazon randomly had this Bucchigiri Nendoroid listed for $10 (plus a coupon that made him $8), so I bought him.
Couple hours later Amazon updated the listing to $49.
Lesson here is Always Check Amazon.
Every. Single. Day.
It's like "The Last Bus to Bikini Bottom" from SpongeBob, the day you look away from Amazon is the day you miss out on something you actually wanted for a better price.

Worth noting about 5 days ago, "My Wife Has No Emotion" Nendoroid was listed on Amazon for $22.
And back in August, the "Chiaki Nanami" Nendoroid from Danaganrompa randomly appeared in stock by Amazon as the seller for $45 with 15 of them in stock.
She sold out in about 2 hours.
