Home Depot is having a killer Bathroom Vanities Sale right now.  They have all sorts of makes and models with a ton in stock for you to take with you.  If they are sold out of your particular vanity that you have your heart set on, just ask one of the friendly sales representatives and they can call another store and try to find one for you.  They can also order you another one if they can’t find any more at any of their other locations.  Make sure to ask about the time frame when ordering as that can vary.
