I have been using software for 30 days and using Walmart as my supplier with free shipping. I have been setting the breakeven at 14%, 10% for Ebay 4% for Paypal. I place the profit at 6% or $3.00 whichever is greater. With these parameters I am always the highest seller. I will then search Google for a supplier lower price then the lower seller on DSM listed, but I cannot find one. I have sold about 80 items but I was setting my breakeven at 4% and relying on cashback as the profit, but I found out I can’t rely on cashback as my final profit.
Thanks for your time.
