The alleged robbery took place at the Family Dollar located at 1420 Gulf Bank.
Police said the suspects entered the store for a few minutes, then went outside and hung around the front door.
When the 74-year-old woman walked out to her car, one of the suspects aggressively took her wallet, which caused bruising to her arm.
Crime Stopper is offering up to $5,000 for any information that leads to the suspects.
