Alienware Trade-In Program

Back when I bought my Alienware 18, I had no idea there was a trade in program for my Aienware 18x. To this day I write to the email address and get no reply. I simply want to know if I can trade in my Alienware 18x which is in mint condition collecting dust :) and not being used. https://dell.trade-in-platform.com/_ContentAlienware/Contact.html
