Your morning routine gets a whole lot easier once you swap that dim builder-grade fixture for a bright new vanity mirror with integrated lighting. Installation usually takes less than an hour if the wiring is already in place, but you will want to wait for home improvement store sales around major holiday weekends like Memorial Day or Labor Day to catch the best price on the unit itself.
Before you buy, grab at least two quotes from local handypersons if you are not comfortable messing with bathroom electrical lines. Getting multiple bids keeps labor costs honest and ensures you are not overpaying for a quick mount and hookup.
Remember that the 0% intro APR for 15 months on purchases and balance transfers is a deadline, not free money. If you still have a remaining balance when those 15 months run out, standard interest charges will kick in on whatever is left.
