I was just curious of people's opinions.
A guy is selling the Plans: Staff of Herding for 50k. The same plans that, if you can use, you can buy yourself for 1g from the vendor in Act 4.
He said it himself, he's banking on the fact that people don't know you can buy it from the vendor.
Is that considered a scam, basically getting money from people due to simply not knowing something? If so, is that any kind of violation of Terms of Use?
