I got an email to upgrade my current Birchbox to Birchbox Plus! For an additional $20, I can get a necklace (worth $30). I love the idea of Birchbox expanding, however, with all the different accessories boxes out there, $20 for an extra necklace might not be worth it. (Think BaubleBar/JewelMint, etc) If it was for an extra $7-8, I would consider it. For Birchbox members, they should definitely be giving us a perk!
