So, this can work, but here's exactly what happens. You find a product on Tactical Arbitrage that sells on Amazon at a pretty good margin, and you buy a lot of it, but by the time you send it in 30 other sellers have done the same thing because they all saw it on TA as well. So now you're in a price war, and you're either forced to sell it at cost (or even a loss), or you have to wait for 2 or 3 months for the other sellers to run out of stock. I'm not saying this can't work. I've found some good products to sell, but it was more from my own research and not directly from TA. It's a pretty good tool though for knowing if you're eligible to sell a product and the history. EDIT: I stopped using it after the free trial because I didn't think it was worth it, but I encourage you to try it and see what you think. Answer from king-schultz on reddit.com
