PHILADELPHIA — A woman pleaded guilty to scamming the QVC home-shopping network out of more than $412,000 by exploiting a glitch in its Web site.

Quantina Moore-Perry, 33, of Greensboro, N.C., did not pay for more than 1,800 items she received from QVC between March and November 2005, authorities said.

Moore-Perry ordered handbags, housewares, jewelry and electronics, then immediately canceled the orders and received credit for them. But the glitch caused the items to still be delivered to Moore-Perry, who subsequently sold them on eBay, authorities said.

QVC became aware of the problem after being contacted by two people who bought the items, still in QVC packaging.
