OK.
If you can manage to join @Betfair.com, you can lay or back and make some cash. The secret is to speculate right now. If you feel really strongly on the subject, depending on what side you want to win, you can have a flutter, your side loses, and still be happy on the 19th Sept. That's what I did.
If YES wins, I, as a NO voter stand to make a £429.57 profit. (I started off with a £200 free bet from @bet365.) I blew the first £100 on Dundee United to be runners up to Celtic last year. How pish am I at fitba betting eh? Am terrible.
So, give it a twirl. Open up an account that flings free betting money at you, keep mind you need to roll that free money over three times to get "free cash" but it is worth it in the long run. Here, I used to back a horse called Long Run years ago. So, aye, give it a bash. The 1/7 izny very appealing from your point of view mind.
