Promposals aren't just a viral trend, they are now the most expensive prom cost for some. A study by Visa Inc. has found that an American household spends an average of $324 on promposing, and parents are increasingly footing the bill: In 2015, parents paid for up to 73% in of prom costs, up from 56% in 2014. Companies like The Heart Bandits are cashing in on the trend by charging upwards of $1000 to plan promposals, and brands are as well: Men’s Wearhouse Inc. declared March 11th promposal day on social media to sell tuxes for the occasion.
