Thanks, OP! The same thing happened to me. It was $5 to sign up with Selects and it automatically gave me a $30 off coupon. I just got onto chat and explained the situation and they gave me another $20 off since the promo didn't work for me either.
After the store closed last night, Target app said they had stock. Go in at opening and said sold out and I was one off the first in line. No where to be found and grabbed a worker who couldn’t find the only copy they had anywhere. Searched the clearance end caps and boom, hidden with the other...
She was in stock at around 8 am PST Sunday and sold out within the hour. It's not coming back in stock as that was their only shipment and is now discontinued from their system. I'm sorry about this.
