Since the pandemic, the average mortgage payment has jumped from $1,427 to $2,047. That's an extra $600 every single month just vanishing from people's pockets. Meanwhile, credit card debt is hitting record highs, and savings accounts are at their lowest since 2008. Most folks are left with two options… Get a second job... or work overtime on weekends. But what if there was a third option? I just uncovered a shocking anomaly in the options market that could change everything... One that lets you target extra cash on days when most people make nothing - weekends. Think what that could mean for your monthly budget...
