Recent developments in group buying have led to a wide increase of appearances of similar phenomena in Europe and North America. While the original strategy for group buying in China was self-organized and executed, most of the group buying in Europe and North America is done only through online intermediaries. Interested buyers are, most often, asked for credit card details, which will be charged only when a required number of buyers register. Almost without an exception, intermediaries charge vendors a percentage fee in the range of up to 50% of the total value of the whole deal. Due to this business model, group buying remains limited to the physical services sector and is not seeing growth as with the original strategy in the People's Republic of China.
