I picked up the last one they had at one store and when I went to check out, it rang up the original $90. I didn't realize the ad I saw was wrong and showed them their own ad paper. After discussing with higher ups for a while, they allowed me to buy just one (was a last one anyway) at the error ad price and they put up ad correction notice since the ad is still good through tomorrow.
One $90 new set for only $20. YMMV, find Walmart store that has this set without the ad correction notice and bring ad paper. I did not try for price matching at other store. The ad is a thin 1 sheet 4 pages all toys ad that either came in newspaper or may even be available at the doors.
I am attaching picture of sales receipt if you want to print it out and show it at Walmart that someone was allowed to buy a $90 set at $20 price.
