I know I am being a bit silly but I'm getting slightly nervous about a parcel I sent out 2nd class signed for. Delivery was attempted 20th March and parcel was returned to the delivery office. Buyer has now had 2 Saturdays to collect but has not done so. Obviously it's up to them when they get it and they might work weekends but I'm just a bit surprised. I'm wondering where I stand if it gets sent back to me?
