If you click on the higher end designer bags on the TJMaxx website you'll notice that they will say "not returnable in store" so that's how they can protect the consumer against fakes.Oh I definitely agree with you about the saving money part!
I was also concerned about the authenticity of the bags, because I can't help but think someone might do a bait and switch and are the stores trained to know? Some of the bags I've seen on their (TJ Maxx) website are $1500+!
Good for them! I guess if you don't love your $1500 handbag you just have to mail it back to them!
