Groupon offers the U.S. Traveler 5-Piece Rolling Luggage Set in Blue or Black for $79.99 with free shipping. That's tied with last month's mention as the lowest total price we've seen for any U.S. Traveler 5-piece luggage set. (It's a current in-stock price low by $70.) It includes an upright rolling suitcase, rolling duffle bag, upright carry-on suitcase, garment sleeve, and TSA-approved clear toiletry pouch. Deal ends March 9.
