Consumers misuse of Wal-Mart's price match program isn't limited to the PlayStation 4. But shoppers may find it's no longer so easy to replicate the feat. After Wal-Mart announced Nov. 13 that it would price match select online retailers, including Amazon.com, several customers used the program to buy $400 Playstation 4 consoles for under $100 using fake Amazon listings. Twitter and Reddit users posted pictures of receipts documenting PS4 prices as cheap as $90. "Sounds like Wal-Mart needs to trust, but verify," said Edgar Dworsky, founder of advocacy site ConsumerWorld.org.

Did Sears.com pad the bill for major appliance orders by automatically tacking on a service contract even when it's not requested? Edgar Dworsky, a nationally respected consumer advocate, made that claim last week. Sears said on Dec. 2 that it will change the way its website operates.
