Update – Nov. 13th: These are starting to show up at Toys R Us stores in the US.
This year’s Mater Saves Christmas single carded Cars have begun showing up in the UK. So far, we have Whee-Hoo Winter Mater, Snowplow Lightning McQueen and Holiday Spirit Sheriff. Hopefully, these will show up in the US soon. My guess is they will be showing up at Target and Toys R Us, same as last year. Here are the images.
