That's what they're trying to accomplish. Still probably not a bad deal for someone trying to crossover.
A better promo would read: "$10 crossover strikeout challenge". People have a better understanding from the get, plus it implies a "challenge" or accomplishment for "hitting" with the crossover and not "striking out" with the $10 promo charge. No more free marketing ideas from me. Pay me and I'll gladly do the job.
