These clearance prices have been out for at least a week and I was expecting to see it on here, but I haven't seen it posted and I still saw some on the store shelves after getting my kid's fill of Peppa Pig toys.
Some of the sets are as low as $3.00. And these are play sets with multiple characters, a car/building, accessories, etc.; not just one item. I have linked the Walmart.com pages for reference, but obviously as these are YMMV clearance items, the prices on the website DO NOT reflect the clearance prices.
I have also linked the brickseek links. And as per usual, brickseek is not 100% accurate. Some items say there is no stock, but I literally just saw some on the shelf earlier today. I will attach some pictures of some of the clearance tags to this post if possible for reference as well.
My particular Walmart had the clearance items in the main toy section that contains the Peppa Pig toys AND also in the designated toy-clearance aisle. So check multiple places.
Peppa Pig Peppa's School Playset - as low as $3 in my area
Peppa Pig Grandpa Train - as low as $3 in my area
Peppa Pig Family Campervan - as low as $5 in my area
Peppa Pig School Bus - as low as $9 in my area
Peppa Pig Grandpa's Boat - as low as $9 in my area
