No. This is not a real check and you should not cash it.
Sentry pays the majority of shoppers by direct deposit. We NEVER send a check in advance of completing an assignment.
If you received a check bearing our logo and asked to deposit it and then buy gift cards or wire part of the proceeds, it is highly likely that this is a SCAM and we strongly advised that you do not cash this check.
You can always email our help desk with any questions or concerns regarding payment or the validity of a check sent to you.
