EdTech uses eTechCampus for all buybacks. Therefore, once you sell your book to eTechCampus, you must contact them for support. If you purchased your books through eTechCampus last year, sign in and sell through your account for the best results. eTechCampus also uses "sellbackbooks.com" as their general buyback site if you did not purchase your books through them last year.
We pay to ship your books!
