Camera Stop

Review: Went into the store to buy a memory card for my camera. The sales associate convinced me to buy a $50 memory card & told me it would fit. I took it back to the hotel and discovered it was the wrong size and wouldn't fit my camera. They wouldn't give me a refund or exchange and tried to sell me a camera for the newly purchased memory card. The camera they showed me started with a price of $149, then went down to $139, & finally $129 before leaving the store. The camera they tried to sell me cost $79.99 at Sears & Best Buy, & K-Mart. Also the memory card that I bought for $54.49 sells for under $10. at most stores. Sony Memory Stick PRO-HG Duo. MS-HX8B. Sony Cyber-shot Camera DSC-W710, 16.1 MP.Desired Settlement: I would like a refund for the $40 that I over paid.
