My order processed before I could enter a discount code. I feel this was because my AMX card was hard coded into my account. Possibly if I had known I would have been more cautious.
I did get confused when I received my shopping cart and the 40% off discount through my email. I was on a thirty minute deadline to keep my cart items. Had intended to go through and clean it up but then with the 40% I just went for it. Of course my code didn't go through and I found out if I had read carefully I would have known I didn't qualify for 40% because at some time I had used it for a pair of shoes.
The resouolution from ThreadUP was applying a 10% discount which I did have.
The very next day I received an email inviting me to spend my credit which I had used on my order.
In a nutshell I believe communication could be better. For example threadUP shows my free shipping up when I shop yet they had been showing my 40% off.
Even though it says for first time purchase I believe it is misleading when they send it in a personal email. The company is aware I don't have 40%.
I was mislead.
