When we went to get ours the other week, we were advised by the assistant to consider whether that trip would give us the opportunity to use the vouchers due to 3mth expiry. We therefore decided to wait until Easter when I plan to make full use of those we can.
For anyone going out to complete and furnish, I would advise you think about doing the same, as in 8days, we really had no chance to get any benefit from the discounts had we taken them
