The items listed here may or may not be in your local store (YMMV) but I will provide a link so you can check local stock and local prices.
The website used to check stock is not a guarantee but is usually close to what it says. It is not a price match tool. You CAN NOT use Brickseek to price match at a store. You can check price in-store with the price scanners and the Walmart app also has a scanner.
