asda sells DSlites for £89.97 in the UK

Today I went into Asda and looked at the gaming department only to find for this week only the DSlite will be priced at £10 less than RRP. I will be getting my Lite later today as a package from HMV with trauma center and brain age along with a accessary pack on a buy now pay later deal, so I can pay for it when I do get paid.
