BOSCH PCQ715B90E Gas Hob - Brushed Steel 5 burner Gas hob which is currently at £279 at Curry's has a trade in code of BOSTI30 for £30 off for trading in your old appliance. However it is taking £45 off the total price making it £234!!
I used the code and did not trade-in anything, nor did the delivery person ask for a trade in.
This hob has very good reviews on Which and not available at this price anywhere else.
