Today, I found that I can make LOADS of cash tanning!
Tanning Red Dragon hides or Blue Dragon hides!
Blue is about 150-250k per hour and the red is about 300k-400k per hour but red dragon hide cost more so u get less from the G.E but its about 250-300gp per hide!
Blue dragon hide is cheaper so u can get more but its about 150-250gp per one. Means you can bot more in one-go! (depends on the G.E)
I recommend u use this because u can get so rich! Made like 1M in like 1-3 hours!
Its also great because there are NO requirements need to tan them! (I think, lol

)
What I did!
I used RsBuddy with the bot, 'ArteTanner'.
Then tan them in Al-Kharid!
When you sell them in the G.E, it may take a few hours because it doesn't usually sell straight :S
Hope you found this useful!
