You buy the Moshi Mash Up cards in stores and from the Moshi Monsters Online Shop.
Moshi Monsters Mash Up Cards were released in late 2010.
It depends on which kind of cards you are asking about. ASDA does sell Moshi Monster Time Cards (for paid membership on Moshi Monsters) in their stores. You have to ask at the counter for the Time Cards. However, there is no information that shows ASDA sells Moshi Monster Mash Up cards.
Each pack of Moshi Mash Up cards contains 6 cards, including 1 Secret Code Card.
They come with Moshi Special Codes. If you buy the mashup cards you get codes on some of those. (The Map cards have the codes)
