Group buying involves offering products and services at significantly reduced prices on the condition that a minimum number of buyers purchase them. Each day, a deal is featured on social media and email newsletters. Customers pre-purchase coupons and share the deals to help meet the minimum threshold. They then redeem the coupons at the merchant to receive the discounted items. Daily deal sites have changed online commerce and given businesses a new marketing channel, with some sites selling for millions despite only operating for a short time. However, group buying is still in its early stages in Wollongong.
