I like to compare it to the research done on olympics and their economic impact. Big investment in hopes of a strong injection in the economy. The opposite happens, once the event is done, the facilities/stadiums/everything goes unused -- novelty and interest lost. Same thing happens to these business when they worked with Groupon: make some money (oftentimes they don't even break even) during their promotions/deals, but as soon as it was over hardly any bothered to return.
