Free Double Deluxe Upgrade on the BarkBox Birthday Box

BarkBox's Birthday Box is the themed celebration delivery — party-styled toys, treats and a chew built around your dog's big day — and this offer adds the Double Deluxe upgrade at no cost. Double Deluxe doubles the toys and treats in the box, so the birthday delivery arrives with four toys and four bags of treats instead of the standard two and two. For a box that is already the most gift-like in the BarkBox range, doubling the contents for free is the version most people would have paid to add anyway.
