Question: I am a seller and wondering if I’m paying too much for service.

Hola everyone! Have a question. I am selling all kinds of products from many distributors. It’s impossible for me to go through literally hundreds of thousands of products and calculate profit from those distributor’s price lists. I found a Canadian company who analyze all products I send to them. I am paying $1 for 1000 products and they give me full report with profit ROI% lowest price highest in history and much more. But main thing is to see what profit. Does anyone know cheaper companies or is that a good price?
