The Lego Game Boy isn’t supposed to go on sale until October 1st — but I already bought one and built it for you. How? Costco and Sam’s Club have pallets full of them at warehouses across the country, they’re already on sale at a discount, and I’ll tell you how to check if they’re at a Costco near you.

Both stores are selling the brand-new set for around $49. That’s a big discount compared to the $59.99 you’d pay at Lego or at Amazon, and some who ordered early through Lego or other stores are annoyed! But, neither Costco nor Sam’s Club is likely to let you buy without a paid membership. (Costco’s is $65 a year.)

The picture atop this story is my local store, but they’re already available in far more locations. Here are piles upon piles of Lego Game Boys spotted by Redditors across the country, most within the last few days:

How do you find out if they’re at a store near you? They’re not listed on the web, but you can use a feature in the Costco app for iOS and Android that lets you check warehouse inventory.

Open the app, hit the Warehouse tab at the bottom of the screen, pick a local warehouse, then tap “Search Warehouse Inventory” and search for 1917022. Then tap the “Lego Nintendo Game Boy” item, tap Find Nearby at the bottom of the screen, and you should see a list of every warehouse where it’s in stock near you.

You’ll still have to go find it in store; in many cases, it’ll be in the toy aisles alongside other Lego sets and not far from candy and clothing. In my case, it was right inside the entrance. Maybe my Costco was hoping to sell a few more memberships that way?
