They are efficient and misleading
I ordered a sweatshirt with a saying on it and it has been processed very quickly. However, I received 2 further emails the next day from the company saying I had left the item in my cart. I went back and purchased it only to receive 2 more emails of that ilk. I checked my account, which had been charged twice. They refused to cancel the order and on day 3 have already shipped both sweatshirts.
