PITTSBURGH (NewsRadio 1020 KDKA) – You buy a new TV, video game system, or a new printer, and when you get home, you find out you need an expensive cord or attachment that didn’t come with it.

Maybe the salesman tells you about an expensive cord for your new TV that he says you need, but maybe you don’t.

It’s called upselling, and it could cost you extra money that you don’t need to spend to run your new technology.

KDKA-AM’s Larry and John talk to tech expert Jennifer Jolly of  Tecca.com about what to watch for when you buy new technology.
