If you search target.com you won't find the Wii console in the listings any more, but I took a look at the URL of another product (the DS) and it became apparent that it was a simple matter of replacing the ASIN in that URL with the ASIN for the Wii. I looked the Wii's ASIN up on amazon.com and plugged it in. Specifically, replace the "asin=B000I10PY2" from the black (onyx) DS page (or whatever ASIN for whatever product you are looking at) part of the URL with "asin=B0009VXBAQ". Viola, you get the Wii console page, with "Find it at a Target Store" button intact and functional. I have no idea how accurate their listings are, but perhaps it is worth mentioning:
