Been looking for a new carry-on hard shell suitcase and thought this was a good deal for a decent brand. This particular model, Light Max, has the lightest weight (2.3kg) for the highest volume (40L/44L), from what I can find. There might be others out there, but not in this price range. Different colours are available.
Discounted price is $144. If you sign up for the newsletter here: https://www.americantourister.com.au/on/demandware.store/Sit…, you'll get an additional 10% off code which brings the price down to $129.60.
Not sure if the other sizes are good value, but they are also 40% off.
Was just over $100 at Catch last month.
