William Hill's app "up to $100 cash back"

Would $1000 in straight sports betting get $100 cash back in this William Hill sports betting app? The part I do get is that the bets have to be made by April 30, 2015. Or am I interpreting this wrong and need to bet $100,000 to get $100 back?

My interpretation is that $100,000 would need to be wagered to receive the $100 bonus for straight bets. Parlay cards or teasers earn more points per wager.

$1,000 in wagers equals $1.00 "Bonus". $100,000 in wagers earns $100.00 Bonus. If only parlay cards are wagered, than 5x points would mean only $20,000 in wagers would qualify for the $100. Betting teasers would need $50,000 to max out the bonus.

I'm not a sports bettor very often, but it seems to me that some of the offshore sites offer better promotions. Usually your deposit is multiplied, but there is a requirement that the money must be put through several times before cashing out. If it's a site you trust, those would, off hand without doing a bunch of analysis, would seem to offer the potential of a higher return, and a much longer time frame to complete the obligation.

Thanks Roadtrip for the interpretation. I guess I can forgetaboutit with this promotion for "earning up to $100," it would take me 20 years to place straight wagers totaling $100,000 to get $100 back, and by that time the promotion would have expired long ago. I would rather "jump through hoops" with the strick off shore books obligations than risk $100,000 for $100 anyday.
