After seeing this thread, went into gamestop yesterday and they had no fucking clue what I was talking about. Told them it was a dlc code on the Wii U eShop for $4.99. Left cause no one could look it up.
Went back today to a differenjt store and though they didn't have the yellow eShop box on the shelf, I grabbed the Luigi U one as an example for the cashier. Explained I would like to buy the Wii U Sports Club Tennis code for $4.99, comes in a box like the Luigi one and it's a code I buy to download on the Wii U.........It took FOUR gamestop reps to find this code on this comps *facepalm*
For as much as gamestop is trying to advertise they sell dlc, they had no frickin clue what this was, let alone a Wii U
Edit: THANK YOU op. You are awesome!!!!
