Benjamin Edelman and Paul Kominers have a fantastic post up about the various legal pitfalls facing Groupon and other coupon sites: there are more of them than you might think. In many states, for instance, it’s illegal to offer discounts on alcohol, yet Groupon merchants do so anyway. In others, coupons need to have a 5-year expiration, rather than the much shorter ones found on most Groupons; it’s not enough just to offer the consumer’s money back for that long. Elsewhere, people redeeming coupons for less than the face value are required to get the difference back in cash. And it’s also quite common for merchants to need to hand over to the state any money they got from expired coupons.
And then there’s the question of sales tax. Let’s say I spend $20 for a $40-face-value Groupon at a restaurant. I rack up a $60 bill, before tax and tip, and the check arrives, charging me $65.32 after adding 8.875% sales tax. I hand over a Groupon and a credit card, and my card gets charged the difference, of $25.32; I then add a tip on the $60 amount. So far so normal.
But in fact, once I hand over the Groupon, the sales tax should be recalculated — this according to unanimous advice from various state authorities. Rather than charging tax on $60, the tax should be calculated on the post-coupon amount plus the amount that the customer paid for the coupon. So in this case that would be $20 plus $20 makes $40. The restaurant is charging too much sales tax. It's only $1.77, or 8.875% of $20, but that is essentially a hidden gift which goes directly to the restaurant. (But not to the server! So don’t use this as an excuse to tip less!)
Those sales-tax amounts quickly add up:
The big picture here is that Groupon and other coupon sites are being unreasonably aggressive in trying to slough off legal responsibility for these issues onto their merchants. This bit is worth quoting at length:
Andrew Mason, Groupon’s CEO, is the smiling face of customer service which exceeds expectations and keeps everybody — customers and merchants alike — happy. So it’s worrying to me that he’s set up his company in such a manner as to make it seem that these important legal issues are not his problem.
Groupon is swimming in money these days: it should spend some of its millions on some decent lawyers and set a high standard in such areas for copycat sites to match. Otherwise its much-vaunted customer service looks as though it’s entirely cosmetic, and serves to disguise the fact that Groupon is helping merchants flout consumer-protection laws across the country.
