Sean Jeardoe, 20, was arrested outside the West Seattle Thriftway Sunday.
Police said he was driving a stolen Nissan Frontier. It was loaded with stolen property like laptops and jewelry taken in home burglaries and car prowls. There were so many items, police said it took hours to catalog and process the evidence.
There was also a .22 revolver and a shotgun in the car.
Jeardoe is now in jail on suspicion of vehicle theft and possession of stolen property.
A woman who was seen leaving the truck and walking into the grocery store was also arrested.
Jessica Detrick, 33, is in jail on charges of unlawful possession of a firearm and for failing to appear in court on an attempted burglary charge last year.
