As was previously announced, Walmart locations were supposed to be running a Detective Pikachu promo event today. From 11 AM to 4 PM, participating Walmart locations were supposed to be giving out a Pokemon TCG card featuring Bulbasaur art from Detective Pikachu, as well as a Detective Pikachu poster. Nintendo said these items would be limited, so make sure to hop on them as soon as you could. Unfortunately, it seems numerous Walmart locations didn't even bother to set up plans for the promotion.
Numerous fans have taken to Reddit to share their experiences in trying to get the TCG card. Some locations didn't even know that a promo event was set to run, and various employees couldn't be bothered to find out more information. These are locations that were promoted as participating in the event.
If you have a location near you that's supposed to be participating, don't give up! The cards should be available somewhere in the store, and hopefully if you pin down the right person, you can grab this limited-time item.
