If you find the mats yourself it is like 4-5 times cheaper than to buy. The people undercutting are the ones who can afford to due to this. I make 250k a day just on stims. People have to buy them over and over. Implants are a one time purchase. With a business model like that, you would be eaten alive on dragons den/shark tank.
Not exactly what I was saying. If 1 stim costs a theoretical 3k in mats self gathered to craft, it is still more profitable to sell for the mat's for market price rather than the stims undercut 15-17k price.
I make plenty on lowbie implants, so perhaps it is not as unsustainable as you might think.
