It's a shame if they disappear. My Walmart, Target, etc can be pretty lousy with the stock... It's usually been Toys R Us that has come through for me at times and where TMNT stuff is concerned, at least here, the price is barely any different. When I couldn't find the 11" figures from the first movie and they were the last place I checked, I fully expected them to be more expensive but it was the exact same as Walmart.
If they close up, I hope its at least a slow departure and that mine is still around for a while. It's been there since I was a kid, maybe longer.
Would be nice if they still get the last of the TMNT stuff... Lord knows my Walmart and Target can't hardly be trusted to ever get and stock much of it anymore.
