There are finally some listings on Walmart.ca. None seem to be available for pickup, so I'm guessing they haven't arrived quite yet.
They have individual listings for Triple H and Warrior, as well as what I assume is a random assortment sku listed as Rey Mysterio for some reason. As expected they're $20.

They also have the ring for $27, but it's worth noting that this is just the ring alone, not the pack with Cena and Triple H, which will likely retail at $40, which basically means get a ring free with 2 figures, or a ring, a discounted figure, and a free one, depending on how you'd like to think about it.
