Not counting the initial stock, since no one actually grabbed it, Nimi's merch preorder is as follows:
>[PREORDER] Nimi Nightmare Ghost - Plush $40.00 USD
Sold 516 so far which is a total of $20,640
>[PREORDER] Nimi Nightmare Ghost - Keychain Plush $20.00 USD
Sold 438 so far, which is a total of $8,760
For both she's moved $29,400 in merch (preorders). Lowballing it, but if the schoolbags only had 300 in stock (which is unlikely with the preorder sales count and it taking an hour to sell out), she would have moved a total of 62, 400.
