You do not ever want to buy a list! Nothing good will come from it ..
Always build your own list ..
Then again I have a great company that if you set your ad up right you can buy buyer leads for like 50 cent a lead with a super high conversion rate as long once again as you "set your ad up right".
Buy setting you ad up right you have to mention a sale and a price in your ad that way that anyone that gets on your list
is going to be a buyer and will convert.
They are called co reg leads
and I like to use this company.
They are awesome
