Hi! My name is ***** ***** I'd love to help you with your question. Give me just a second to review and I'll back with you ASAP!
Okay, so I think what you are saying is you have a Sony DSC-W180 camera. That camera has a bit of storage on the camera for pictures and uses Memory Stick Duo / PRO Duo card for additional memory. Are you asking where you can get a Memory Stick Duo / PRO Duo card?
If that is your question, here is a list from Sony of all the cards that work with your device:
Sorry, but Sony won't let me link to the exact thing directly. Go to that link and select "Memory Card" from the category of combination products area and you'll see a list of cards. You can do a Google search and find places that carry the card you want to buy. This should let you obtain another card for your camera!
If this answers your question, I would really appreciate it if you would rate my answer. If you need more help, just reply here and I will help.
