From my experience, I've visited TJMaxx a few times in the past few weeks. Most of the luggage items were "junk" quality and models that no one heard of. BUT, during these visits I found a few legit models like Samsonite Sphere Lite (sold at Macy's), Samsonite Launch II and Traveller DLX (Sold at Sears), Travelpro Marquis, Mosaic Quad. All these models cost way more online and in stores than what I've found there (90$ for the 25" size).

But indeed I had to go to different stores multiple times.
