I’ve always used a credit card that had purchase protection. It’s one of those “bonus” features that are found in most non-point cars that I think are really worth it. The TD Gold Select is one of the few cards that offer purchase protection and don’t have a fee. This protection even covers damages to an item you purchased:

Enjoy worry-free shopping with Purchase Security and Extended Warranty Protection. If an eligible item that you purchased in full with your eligible TD Visa Card is stolen or damaged within 90 days of purchase, it may be replaced or repaired or you will be reimbursed for it. If the item comes with a manufacturer’s warranty, you may be entitled to double the warranty period by up to 12 additional months.

There’s plenty of other cards that offer this, some without a fee – so shop around! It’ll protect you from purchasing broken tv’s.
