ASDA is owned by Walmart now, but it's not the "UK name for Walmart". ASDA is short for Associated Dairies, and was founded in Leeds by some farmers. (Ironically farmers are probably now being shafted by ASDA for their produce)
I'll check my local on Friday and get back to you, though I'm not certain they have Vita now... it might change store to store depending on how well Vita stuff sells.
