It is the second time in a week convenience store clerks have been robbed at gunpoint.
Police are looking for two men involved in an early morning armed robbery who robbed the Get N Go on East 10th street.
The latest happened at a Get N Go Friday morning around 3:30 a.m.
Authorities say two black men in their late teens to early twenties held up a black semi automatic hand gun, stole an undetermined about of cash and got away.
Suspect one was wearing a camouflage jacket with a grey hood, black pants and had a white scarf tied around his face. The second suspect was wearing a black hoodie and black shoes and has a "slight" mustache and beard.
Exactly one week earlier, the Shop-N-Cart on east 12th Street.
"It doesn't make sense to me and it never will, but it is what it is. Crime is part of the business and we try to prevent it," Shop-N-Cart Owner Dave Grevlos said.
The suspects connected to the Shop-N-Cart were described as three black men in their late teens to early twenties. They were dressed similarly to the Get N Go suspects, held up a handgun, demanded cash from the clerk and got away.
"There are some similarities there, just in the description of the suspects, but it's too early to say if those are related," Sioux Falls Police Department Public Officer Sam Clemens said.
While police search for suspects, store owners like Grevlos are reminding clerks to be safe.
"They're instructed to cooperate, give them the cash and cooperate in a quick manner. They just want the money. That's all they're there for and then they leave and that's it," Grevlos said.
Grevlos says his employees keep small amounts of cash in the register, and deposit the rest in time-delayed drop safes that they cannot open.
"Nobody's gotten hurt in the history of our 40 years in business. That's a good goal and we want to keep it that way," Grevlos said.
Police are looking at surveillance video the two suspects from the Get N Go robbery in hopes of preventing another crime.
"Well, it seems there will be a rash of them and then they catch them and send them to prison and then it quiets down for a while," Grevlos said.
