I purchased a Sony SDHC memory card for my Sony camera. I carefully opened the package with a razor just in case I would need to return the item Turns out the card is incompatible with our camera.
Wal-Mart will not take back an opened memory card package. Funny, no signs in the electronics department tell you this before you purchase the memory card.
When pressed for an explanation by three different Wal-Mart associates, the answer is that "this is our policy" No explanation as to why this is the policy. I will NEVER buy anything electronic or electronics related from these people again.
