Reasons why you should buy the invites to the tracker you like

1. Save time searching everywhere
2. Probably the price is cheaper than the price of electricity you use to search for the invite (I guarantee in most cases it is)
3. You will probably need to wait too long for giveaway section
4. You won't need to beg anyone
5. In some cases it's impossible to get inside that tracker without buying an invite from sellers
6. They are not expensive at all.
7. Gift an invite to your friend
