Lego Minecraft 21124 559 pcs Walmart BM YMMV the end portal $30

i was in Walmart today and seen this set marked from $57 down to only $30
it wasnt a clearance sticker so i didnt see it at first.
online it shows $40 but instore is only $30
my kids like this set and pretty cheap per piece
not sure how to order online for that price but if you check the Walmart app (just type in Lego 21124) you can see stores around you for that price.
