That is completly fine. I have sold 2 of my cels 
for a bit more than what I payed for them. The 
thing is, I bought them with the intent to keep 
them but then sold them because I grew tired of 
them. I put them on ebay for $10 less than I 
payed but it went to twice what I payed. I did 
not choose to sell it for more and I didn't 
intent to sell it when I bought it. I sold it as 
a collecter, not a middleman. This selling is 
completly fine with me, so is selling when you 
have access to a source I do not, like some 
random cel shop in japan. Does this clear things 
up?

So long,
