Don’t order textbooks from Indoo.com if you need them right away, because they’re a little casual with their shipping. Joe ordered two textbooks on September 5th. Four days later on September 9th, they sent him an email saying they’d been shipped via USPS Priority mail. They hadn’t arrived by the 16th, so Joe emailed to ask what was going on. They responded that actually the books had been shipped on September 11th via USPS Priority and that “the arrival expectation is 4 to 5 business days.” Joe received one of the two books yesterday, on September 17th, which would have been 5 business days after the 11th. Still no sign of the other book.
