We are Satisfaction Services Inc.® -We do not send out large checks to be cashed. There are disreputable companies scamming shoppers.One of the latest and more serious we've heard about is a company sending out large advance cashiers checks. The shopper is told to send a Money Gram or Western Union to a person keeping part of the check for themselves. However, the check is not legitimate and bounces, leaving the shopper without any money to cover the Money Gram."
