Definitely a splurge, but the diptyque car air fresheners smell so good! I have had the same two cents for about 6 to 8 months now and I just switched them off and on every 2 to 3 weeks and then just keep the other one in the bag that it came in and they both still smell amazing after all this time  LTKmorningroutine LTKdayinmylife LTKmomlife
