Yes you can, just remember just we will pay out any Free Bet winnings minus the stake of the Free Bet. When using a Free Bet on an each-way market, the entire stake is placed on both the win and the position.
This means a $10 Free Bet is split between $5.00 on the win and $5.00 on the position.
For example $10 placed on a 7/2, ¼ odds 1-5 places. Should your backed horse then place, half of the stake is put on the position i.e. ($5) x 7/10 + 1 = $8.5.
Deducting the total stake of the free bet ($10) means the payout is less than what was staked.
This means that you will not receive a payout, as it is less than the value of the Free Bet.
