As I've posted elsewhere on DDF, my Target Circle subscription expired, and I was debating whether to renew or to do Walmart+. Members here recommended Walmart+, and I am in middle of working on verifying a WIC account so that I can get it for only $50, but it was taking some time. In the meantime, we needed a bunch of stuff, so I decided to just renew the Target subscription for a single month, and put through an order meanwhile.
I loaded up my cart with all the things that I needed, and since I didn't make a recent order, the total was about $320. I put through the order yesterday, and after it got delayed a few delivery slots, it was finally delivered this morning. I was quiet frustrated, especially since one of the items that were in stock last night was OOS this morning, and it messed me up for a deal of "buy $100 baby stuff get $20 gift card".
I called Target customer service to complain, saying that if the order had not been delayed I would've gotten the $20 gift card. They said that they can't issue a gift card, but will give me a $20 refund. Two minutes later they called back. "Sorry, but there was a technical error. We mistakenly refunded you the entire $320 for the order. But don't worry, you can keep the items and enjoy them for free!"
TL;DR: I got a $320 order for free!
