The Walmart closest too me is alright, they keep their stuff in stock pretty well. The one across town has a smaller selection and is a little slower though.
I'm pretty sure the Wal-Mart I used to work at gets Bakugan shipments every week. But believe me, when we put them out, they didn't last very long. 50 starter packs would dwindle down to about ten in just 24 hours. It was hard to keep them in stock. Just wish they'd use their heads with the display instead of splitting in between isles. Traps and Dekas are in one isle and I don't think people know it.
Yeah, I was hired for the Christmas rush, in the toy department. Good place to be to catch new or rare Bakugan. They stock at night, so mornings would be a good time to check. You can also ask if they're getting any in, but sadly, they won't be able to tell you the date.
