theres a couple scammers going around tring to sell you stuff, they go straight to your email, not to yiur post. 1 is tomrandy856, and the other rolandjimmy01, mostly working on the wanted post. be aware.
Had one almost get me recently - I posted a WTB ad and had somebody contact me saying they knew somebody else with those parts and to email them. Took a chance and did it, guy sent me pictures of exactly what I was looking for. Was about to send money until he insisted on friends and family payment, "my word is my bond" bullshit.
Couple days later I got the same exact PM from a different account. Closest I've ever been to getting taken lol
