A smart video intercom should last you five to seven years without needing an upgrade. It gives you secure front-door access and clear package visibility, so buying a durable, well-built unit once saves you from replacing cheap hardware in two seasons.
Spring home improvement sales are the ideal time to buy last year's top-tier model. Manufacturers release new inventory in late winter, which means the previous generation gets marked down right when major hardware stores launch their spring promotions.
That 0% promo period is a strict schedule, not free money. Set up automatic payments to clear the balance within the 18 months, because any amount left over after the window closes will start accumulating interest instantly.
