I rarely post in a FS thread.

1) THIEVES

"hmmm... so Baby J bought todds turbo kit --- sweet. Now we can look for it."

No thanks.

2) What good is posting in the thread gonna do? I'll PM them directly and say "Yo I got $xxx.xx - that's my offer... if not, good luck".

On top of that - I buy things on here and then tell the seller "just put 'SOLD' in your 1st post... don't put 'sold to Baby J' " and they always oblige. This way the world doesn't know about your new mod.
