I got an amazing deal at Walmart for Batman AA & AC - they happened to have the bundle of both the AC and the GOTY:AA bundled together for 39.99 if I recall - but I put it on lay-a-way til Black Friday and was able to pick it up for 19.99, since the SKU was just for the AC and they had advertised the cheaper price for AC in their black friday leaked ads.
Since the games were exactly the same as if I had purchased them separately with the exception of some shrink-wrap and a little walmart wrapper I would not consider these collect-worthy, in fact, I've since traded in them both to trade up for the CEs.
