Simply terrible. I’ve ordered a book and a few days after asked how long it would take for it to arrive. They reassured me it was shipped already and should arrive within 15 working days. After 15 working days I emailed asking if they could check where’s the book and guess what? They replied me after another 5 days that they ran out of stock and the book wasn’t even ever shipped! So much time wasted when I needed it for school a month ago.
