Gah, my mom's being scammed huh? *UPDATE*
She just randomly received a check for 2 grand today in the mail. She is on her way to the bank right now to find out if it's real or fake and to cash it? She tells me the only thing she can think of was that she signed up from CL (omg I know) some secret shopper thing. I told her it seemed like a scam but didn't know if they were related for sure or not. The check is from something like ChemUSA or something? But their website looks legit, only it's for computers or something like that so I am so confused! We'll know in less than 10 minutes though.
Wow, this post blew up. I am really sorry it took so long for an update. The bank told my mom they will hold it for 5 days to see if it goes through or something, but I have informed her not to pursue anything because likely it is a scam. Not sure how she feels or if she will listen to me. I don't know. Thanks for all your concerns and stories though!
