There are a few steps you can take to protect your expensive electronics and increase your chances of getting your claim approved should something happen to them:
Save all your receipts so you know when you bought an item and how much you paid for it.
Contact your insurance company when you buy a new electronic — such as a high-end TV — so your insurer has a record of the item.
Consider buying additional coverage for your existing policy or shopping around for a new one if you want a higher reimbursement limit for your TV and other electronics.
