Package theft and missed deliveries stop being a daily annoyance the moment you mount a smart video doorbell with a chime kit by the front door. The physical install takes about an hour of basic wiring, and catching the right sale during major online shopping festival days knocks the price down before you even pull out a payment plan.
Since home security gear and installation helpers fluctuate in price, watch the retail trackers for a few weeks leading up to the shopping festival. If you are hiring someone to handle tricky wiring, get at least two local quotes so you do not overpay for thirty minutes of labor.
Remember that the 0% intro APR for 15 months on purchases and balance transfers is a deadline, not free money. If any part of that $200 balance is still sitting on the card when the 15 months run out, standard interest charges will kick in on the remaining amount.
