I've never seen a WP item in "my" Target, ever, but I still keep watching for them. Today, as I looked through the trading card shelves, I saw none, but happened to glance upwards during my search of the shelves and saw a Excel banner, with one ad sheet announced, "Wacky Packages ANS7 Coming Soon". Since I've never seen a WP product at "my" Target, I'll believe it when I see it.
The other day at Target a kid saw me intensely scanning the cards boxes and he asked me what I was looking for. I was a bit annoyed I couldn't hand him a pack and say, "These!"
