I'm relatively new to the world of BJ, and have a question about match play coupons. My local casino is offering a promotion until June 30 where match play coupons are accepted (available in a free local paper). The coupon says "Bet $10, if you win, we pay $20!". The small print at the bottom says "Not valid on double-down; pays even money on blackjack". I am wondering how to figure out how much these coupons are worth.
Thank you for any help you can offer.
