We will just make this simple as possible

DO NOT PURCHASE WII POINTS OFF OF EBAY!

Contrary to popular belief, the stores have an over-abundance of them.  the going rate for points in any store on the high end is $1 per 100 points.  ($20 for a 2000 point card) 99% of stores sell it for this price.  [Shopko sells all theirs for $30 so dont even go there, unless it is close to you and you are going to do an Ad-Match] If you already own a Wii, you can just go online with it and purchase it thru your wii for $10 per 1000 points, with no tax!

To make a long story short... Purchase them at the store or off of the Wii itself, it is safer, cheaper, and readily available. 

And if you got any problems when you purchase them from Nintendo or a store, you can talk to them face to face instead of long delayed emails!
