Project TiệmTạpHóa aims to create an online marketplace similar to Groupon to help physical stores in Vietnam expand their customer base online. Currently, many Vietnamese businesses do not have an online presence, but e-commerce is growing as internet usage increases. The project would help businesses reduce costs through bulk discounts and promotions while giving customers convenient access to deals. However, challenges include ensuring product quality and preventing the business model from being copied. The project plans to use digital marketing strategies like social media, email marketing, and search engine optimization to promote deals and drive customers to the online storefront.
