If I can give a zero
If I can give a zero. I purchased an ebook for my class due to the lowest price online ( TextbookX.com ), this site, which is the child company of VitalSource. The URL they provided SSO to VitalSource site, and in the bookshelf shows a ebook but unable to access. I opened tickets to both companies, along with online chat, no one seems to know what's going on. Ultimately, I contacted my credit card company to resolve the issue. Both companies seem like a scam.
