I'm starting to think that people are not reading the OP as it states how to buy these..... there are so many people asking for blocks without doing what it takes to purchase.

p.s.  The original post with all the information is on page 1.... it's actually the first post.

p.p.s.  There are big red letters in the first post that says "HOW TO BUY A BLOCK"...... reading it will help.
