This has work for me when buying my Wii and 3DSes.
For this to work for you, on the recipet the games or accessories which came in the bundle need to listed and have it's retail price next to it.
Usually in a bundle,they just discount the console and put the games at the price their selling it at.
Here's an example of how the recipet needs to look like- http://imgur.com/TIwBozT
Paper Mario has been crossed out because I was able return it, despite it was included in the bundle.
Basically, you are returning the items that were included in the bundle.
This is a way to get the games you want or get the console cheaper.
What do you guys think?
And how exactly do you return them? Most stores have no refund/exchange for change of mind
