In order to get the deal, you will need to use code ONEDAY30. A life pro tip: You need to add this discount before you go to checkout at the JBL website when you are still in your cart. Otherwise, when you go to review your order, you will not see the code applied. Be sure to check out this daily deal and get it before it expires – or worse, they sell out. We rounded up the best deals so you can just head straight to checkout, once you apply the promo code, of course.
