Super Hexagon is on sale for $0.99 on iOS

Since Crossbourne closed the other thread, I am responding here to this post.

"Firstly, looked again at the cheapest listing for COD Ghosts (Steam) on the eBay Australia and its $59. Do not know where you are getting $50 from."

How often do you use Ebay? How come I can find the listings but you can't? Here's one and here's the other. One sold for AU $50, the other for AU $45. I believe these are the only two sold copies for steam key/gift. I am not including boxed copies because we are talking about Steam keys and gifts only. Boxed copies are a different product.

Are you looking at current listings instead of sold listings? You shouldn't be - those have not been sold yet and there is no guarantee that they will be sold. You have to look at completed listings for analysis.

"Secondary, I was talking about selling on eBay, and last time I looked there were no posting fees in real life...."

There are insertion fees but I never mentioned them anywhere in my calculation. I'm not sure why you are bringing them up. In case you didn't know, if you have sold over 40 items this month, the insertion fee is $1.50 in Australia. I assumed that most sellers would not have sold 40 items, hence I left out the insertion fee.
With regards to the other, more important fee that I included: like I said two times already there is a 10% fee (9.9% in Australia) on the final sale price of the item. You want proof? Here.

And you still haven't shown any proof that you can obtain the game for $44 easily. Give me links, especially since you have a history of exaggerating and cherry picking data. The cheapest I can find is $46.92. Note the first entry on that list is $33.77 - I went to site and checked. The price is actually in Euros and the comparator made a mistake including it in US prices.

Edit: I realized I missed quite a few of the Ebay listings since I thought they were boxed copies and they were not. The average of all copies is approx AU $58 = ~$54 USD. My point still stands. You buy for $47 USD, sell for $54 USD. 10% Ebay fee reduced the money you get to $49. $49 - $47 = $2 profit. Let's add another dollar or two in case I missed more higher selling items. So you earn $3 to $4. This is nowhere near the $20-$25 profit margin (later revised down to $15) you claimed.

For Google, Humble Bundle downloads are the same as any APK you randomly got off the net. It's up to the Humble Bundle app to manage your games and give you the updates. Same as if you use Amazon Appstore really.
