Today’s episode of the Consumerism Commentary Podcast has two guests. First, Tom Dziubek talks with Landy Ung, co-founder of the online coupon and deal aggregation website 8Coupons. Landy discusses what features the website offers and how they use natural language processing to help discover deals.
In the second segment, Tom speaks with Consumerism Commentary founder Flexo about the factors homeowners with extra money should consider when deciding whether to invest that surplus in the stock market or to dedicate it to a mortgage.
