minimum profit margin

[savingsrus1]

I used to sell on eBay using a drop shipper that gave me free access and I paid them when a buyer wanted what I offered.
Over the years eBay added a minimum profit margin. !st there was none, then 10% then 30%.
Between the prices for the product, the fees from eBay and Paypal, I found I couldn't compete with large sellers and make any profit.
Sometimes my total costs were higher than what other sellers had as a selling price.

My question is, Is there still a minimum profit margin? If so, what is it? Or is dropshipping no longer an option for the littleseller?
