I am a drop shipper with a team of VA's that research over 1000's ASIN's daily for my drop shipping Amazon business. We make money with our ASIN's because we have drop shipping sources that are solid. If you are buy box eligible then you will sell them on the rotating box. Long live the Amazon gods!
For a whole $5 US big mac dollars I will provide you 5 ASIN's. Your ROI will vary based on the number of items you sell its a volume based game.
You get the follow:
-The cost on the supplier site as well as what you Gross Profit should be after Amazon eats your profit and shipping costs.
-The GROSS PROFIT on each item.
5 Asin's for $5
