Fish,
You're right. If you make a $500 deposit, te $50 parlay helps. But if you makea $2500 depsoit, then the $50 parlay doens't mean a whole lot, and you end up with a 10% bonus. Maybe I'm spiled, but I view a 10% signup bonus as standard in the industry it only when it gets to 15% or higher that its a real promotion.
