SAMSUNG 3.1 Channel 310W Soundbar w/ Wireless Subwoofer -HW-R60M/ZA $100 Shows $189. . Walmart YMMV ?

I was traveling this morning very early and stopped at a Walmart and they had just put out a stack of these.
It seems it is $120 to $189 at other stores. . . .
If you look at a Walmart online . . . the price will say $189.
But here in this search link and in the B & M store. . . $100
It is the first sound bar item on the left for the search below. . . It IS $100, but for some reason when you click on it. . .. it comes up $189.
But they were marked $100 in the store.
