Shares in web retailer eBay could be worth 30 percent more than current prices as a promised turnaround in its core online-auction business begins to yield results, weekly financial paper Barron's reported.

Investors would benefit from a copious cash flow, stabilizing consumer economy, and fast growth at eBay's PayPal payment service and its Skype online phone unit, the paper said.

EBay looks like a bargain relative to similar e-commerce outfits such as Amazon.com , which have considerably higher price/earnings multiples.
