The Roseville Galleria Apple Store was robbed twice in 24 hours.
Thieves entered the location last Sunday and Monday and stole roughly $20,000 in iPhones and iMacs.
The store has been burglarized four times in the last 30 days. An estimated $80,000 worth of merchandise has been taken in the last two months.
Apple storefronts across California have been a major target recently.
Roseville Police say they've noticed an organized group of two to four people having been casing the store.
Other cell phone stores in the area have also been hit.
Investigators are trying to determine if all four Apple burglaries are related.
No one has been arrested for the crimes at this time.
