The cheapest i have seen was for £5.42/$9.50 (not including P&P or MicroSD Card) There are too many r4 ds card in the market currently. The cheapest r4 ds card cost about 5EUR. But it only support DS and DS lite. The famous card is r4i sdhc 3ds. It support Nintendo 3DS,DSi,DS. So, I suggest you to buy a r4i sdhc 3ds card.
You can get it at Target. Thank you

The cheapest Nintendo DS ever obtained would be one given for free, either as a gift or as a prize. The common price of a Nintendo DS is $139.99 however, these have been on sale for as low as $99.99 during specials such as during holiday season.
You can try going to a nearby Hock Shop.
