Nobody wants to compete. I just shared something I use myself, hoping it could help someone else. Of course, to keep it running, I need to make a profit, since the Amazon API alone won't let me discover so many products, and I need to get product info

If users won't find anything useful, I will simply put it offline and run it on demand whenever I need a new drive.

As many users pointed out, neither DiskPrices' idea nor mine is unique; there are many alternatives with different product listings.

It is only a benefit for the users if they have more choice
