Why?
Just stick £20 in your account, stick a tenner on the first bet and a tenner on the second; then when they've settled you'll get a £10 freebet.

If I stick a tenner on my first bet, I'll need to spend an extra £30 to get my free £10.
nah, you get the free £10 but have to have staked £40 before you can withdraw any winnings from your "promo cash"
Oh, right.
Okay, cheers, dudes.
