Argos - Voucher Code working on Furniture reduced at half price!!
I have found that the voucher code FURN20 (20% discount) works on tables/chairs already with a discount.
I couldn't test on all furniture as some were out of stock in my area for delivery.
But the example above worked, I don't think this code will stay around long, it's such a bargain.
With £6.95 delivery charge and using code FURN20 this dining table and 6 chairs has a further £40.50 of making it £168.94!! Delivered!!
