@Zefir: old friend, Please confirm if this is a legitimate client of yours.

Otherwise we already know who this and we recommend highly not to purchase chips from this user.

Just to be sure that clients get working A1 chips, we'll sell any qty at 20% less than this user is offering.  We are the distributor of these chips btw.

That means $60 per chip.
