BUYany Kellogg’s® participating product between 7/8/19 – 12/31/19. Upload your receipt to get Gamepass codes. You can redeem up to 8 smaller items (so 8 7-week codes) and 2 larger items (so 2 30 day codes). I can confirm that if you have Gamepass Ultimate, it just adds onto that (Xbox site says 5 instead of 7, but it actually gave me 7. You can probably create alternate Kellogg’s accounts to go beyound the 8/2 limits.
Full list of products attached. Includes large selection of Pop-Tart flavors, Rice Crispie Treat snacks, Cheez-it large pack.
