I really despise people like you. The op that started this thread is most likely the creator of the bot as its sold on his website and the seoclerk guy is most likely ripping people off as he got his hands on this bot and is selling it without the right to sell it. But what pisses me off the most is people just like you always thinking they should be entitled to discounts and coupons just because. People work hard on these projects and they deserve the money they ask for it.
I believe the seller sells it there as well. I got the bot through seoclerk before it was promoted on bhw. Then, I did contact the dev a few times and my feature requests were implemented quickly.
Anyways, chill bro. It's true though that OP doesn't need to justify the price difference. If you want to get the cheaper source, go on ahead.
