I have been looking for a decent budget priced dishwasher recently and came across this one from TESCO for only £189.97 with free delivery and free recycling of old machine. AAA performance on washing, drying and economy.
MUST USE VOUCHER CODE - TDX-KPRT FOR THIS PRICE.
Don't forget Quidco too on top of this.
It retails generally between £235 - £296 elsewhere (Google Shopping) Comet are are 279.99!!!
