They charge delivery fee for every item you ordered. For example, in my case, I ordered two educational posters for school and instead of receiving them together, they sent them separately, just so I would be forced to pay delivery fee twice. It goes without saying there was no mention of this when I placed the order, which means what I agreed to pay on the site is different from what they actually charge when they deliver. I read on a blog they did this to someone who ordered seven books. Seven books, seven times the delivery fee. It truly is a disgusting policy for a company.
