I ordered a kitchen in the black Friday sales and paid a deposit. I have just found out the kitchen will be cheaper, it is also offering £300.00 to unquoted customers and a free appliance. If I went in after Christmas would I be able to get the kitchen at the lower price and an appliance. Yesterday I received a text promoting the sale. Could you please let me know where I stand. If I would get all the discounts they are offering, the £300 and free appliance.
