I am a big fan of Groupon, not particularly their offers – I have never bought anything through them, rather I admire what the company has achieved in such a short time. It only shows how the Internet can enable new and exciting models.
While the promotions that Groupon offers are attractive for consumers they are quite expensive for businesses with certain cost structures, for example businesses with a higher incremental cost of sales. It is obvious that if, for example, you teach a dance class and have some empty space in your class, adding additional students costs close to nothing. If however you are selling clothes with a 50% profit margin, giving a 50% discount and further sharing the income 50/50 with Groupon is expensive.
I have recently heard a number of people mention that, they bought Groupon deals and as well as paying half price, they also received half the service.
If you consider why a business would use Groupon for a promotion, there are the obvious reasons – to attract new customers, even at a break even or a loss, in hope that they come back and pay full price at a later date or, in the case of businesses with higher profit margins, to generate a large number of sales and hence profits.
If you are trying to do both, by degrading the quality of your service to reduce cost, you are probably unlikely to succeed. Unhappy customers are unlikely to come back and pay full price. Even if they do not realize that they are getting less than normal customers, based on their experience, they are unlikely to think that your service is worth the full price.
If the cost of running a promotion on Groupon seems too high for your business and the loss is prohibitive, then this way of promotion may not be right for you, or perhaps it may be more appropriate to consider one of the smaller players (Groupon clones), who would be willing to charge a smaller commission.
