shopping coincidence

On a coach trip to the Lake District, a couple of years ago, we stopped at a large shopping outlet where I bought 2 bedside lamps in the colour and size I'd been looking for. On returning to the coach I placed the package on a back seat where other people had put their shopping and didn't look at them again until I arrived home. To my amazement the lamps were a different colour to the ones I'd bought but otherwise identical. I telephoned the outlet, was put through to the lighting shop and was told that 4 lamps of this design had been sold on the day in question but as there were a lot of coach parties there that day I thought I'd never find out who the other customer was. As a last resort I rang the coach company and asked if anyone had been in touch regarding having the wrong purchase; no one had, but they gave me a contact number for the coach driver and his wife (who was also the Courier for the trip) and when I spoke to her she said SHE had bought 2 lamps but hadn't yet unpacked them. It turned out that, indeed, I had her lamps and she mine - identical except for colour! I still think it an incredible coincidence!
