It's different in that diskprices doesn't make money for the OP, while it only costed the OP 15$ in claude credits to slopvibe a competitor.
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
