In addition to 1001bricks reply, it is important to take notice of the fact that
BrickLink itself will do NOTHING should anything go 'wrong'.
The BrickLink platform is just a marketplace, and BrickLink doesn't mediate
when there is a dispute between a buyer and a seller. There are some interventions
for sellers or buyers not following the rules around here.
There is NO marketpolice or anything like that, so indeed, take some time
to get familiar around here and feel free to ask .
