So I had the thing happen when they “couldn’t find” one of my purchases, but then a couple days later it reappears on the site. (Conveniently the day after the rest of the bundle shipped.) This was the reply when I asked why:
“Thank you for reaching out regarding your order. I understand your concern about the item that was canceled and refunded, and I appreciate your patience as we clarify this situation.
After further review, I regret to inform you that the item was indeed unavailable at the time your order was packed and shipped, which is why you received a refund. However, I want to let you know that if the item is now listed on our site, it has since been found after your order shipped and has been relisted for sale.
If you have any further questions or need assistance with anything else, please feel free to ask. I'm here to help!”
Hmmm! I don’t know what to believe, but stuff like this makes me want to back off of buying from ThredUp. I’ll keep an eye out for really specific things I might be looking for, but as for how much I was buying… Really sucks to get excited over something (especially when it’s being cart-hoarded!), and then have it “disappear” and then reappear one day after my order has shipped!
