Three-and-a-half trillion dollars. That's how much e-retailing generated in 2019, and by the year 2023, online sales are expected to account for 22% of all purchases worldwide. Adah Rodriguez and Paul Myers-Bennett of the Better Business Bureau of Southern Colorado joined host Shannon Brinias on Thursday's "The Extra" to talk about the next frontier in online retailing, and how to spot and protect yourself from online purchase scams. The guests also discussed their new BBB Business Impact Report, and how listeners can see more of their findings. For that report and more information, visit bbb.org.
