Can't find this deal posted via search so I'm posting it now.
I was looking for an SD card for my daughters DSi and found these at Tesco. I picked up the Tesco 4GB SDHC one in store as it's quite a good price for the high streets.
You can get them off Tesco direct but they are selling them in-store in the battery sections or electrical sections, I found them at three of my local tesco stores.
I can't see who the white label manufacture is but they are selling xD cards in the same packaging made by fujifilm so I'm guessing it's fuji.
