Walking into a home with clean floors without lifting a finger changes your daily routine. Instead of spending half an hour every evening dragging out a vacuum, an automated dock handles dust and water refills for weeks at a time.
To avoid paying full price, wait for major retailer deal days in mid-summer or late fall. Get price quotes from at least two different stores before you buy so you know you are getting a real discount.
Keep in mind that a 0% intro period is a strict deadline, not free money. If you still carry a balance after 18 months, standard interest rates kick in on whatever is left over. Pay your $50.00 every month on time so you finish before the interest starts.
