Rossy confirming that Io's farewell was the biggest house Stardom has ever drawn at Korakuen Hall 
 
She sells her merch independently of Stardom, keeping 100% of the profit.  You can assume every last one of the people who attended spent 
at least $30 on average at her merch table. I posted a pic of her merch line above, they were lined up around the block. 
So she must have easily cleared >$40k just in merch alone for that one show  
 
Idk if I believe Meltzer that she'd accept less than that as a yearly salary to join NXT.  
Sidenote:  Io selling her shyt independently meant that literally the only way to get your hands on any of her merch was to attend a Stardom show in person and wait in line.  There are a TON of international stans thirsting to buy an Io Shirai t-shirt.  Watch WWE fukk that up by releasing some ugly bullshyt and/or one of those damn oil painting t-shirts they keep spamming.
