Many people will say making a stolen item claim to the police is pointless because the value of the item it not high enough to warrant a police investigation. Many times the police will even tell you it's pointless because they do not have the time to investigate and to instead just claim on insurance giving them a crime number.
Now the thing is, what the police say might be true BUT it is still very important to report the theft because of one thing, the companies insurance company. Depending on which country you live in, companies are supposed to have employee insurance and liability insurance. When the companies insurance renewal come up, their insurance company will check things that could affect the renewal price, things such as how many insurance claims has been made against the company, how many small claims (small claims court) has been made against the company, how many police complaints have been made against the company (this includes theft). Insurance companies have access to certain police figures so how bad do you think it is going to look if the company has a large number of police records of theft against it? The insurance company will look at this and assess that the company has a worse liability than before and thus the insurance company will massively increase the cost of the insurance renewal. Company bosses will see the massive price hike in the insurance renewal and will start asking questions as to why.
Companies can hide a lot from insurance companies to avoid massive price increases in their insurance policies but one thing they cannot hide is police records. Granted it does not really help the customer who has lost their item BUT in the long term it will have an affect on the company because if the company is a large company, it could be the difference have say having a $3 million liability insurance cover to $10 million because the insurance companies considers the company to be at a greater liability risk and that is all because some company employee's could not be bothered to take care of customers packages.
So to the OP, report the theft to the police because it will make a difference.
