I just had a fairly interesting experience with lego concerning the ninjago polybag. So I called them up to complain about the hilt of the katana being the wrong shape. Now this may not seem like a big deal to most people, but one of the reasons that I got it is because of the shape of the hilt. You see, the new ones are kinda square, but the old ones are octagonal. In the directions and on the cover it showed an octagonal hilt, but in the set, I got a square one

. So I called them up to see if they would replace it. Well, It turned out that since they aren't directly selling it, they aren't responsible

(never mind that they produced it) When I told him of the discrepancy between the cover and the actual set, He pretty much told me that the cover does not necessarily reflect the content so they aren't obliged to replace it.

This was quite a shock to me. :o So he told me to look at the inventory list in the back. BTW there is no inventory list for this polybag. He finally agreed to send me a sword if I could find him a set that came with it. I found one of the spinners that had it, so they shipped me the katana. So in the end I got my sword and they managed to preserve my loyalty.
