Instant colour

We decided to brighten up our balcony. A couple of pots of zinnias from our local nursery did the job nicely. We bought these last Friday. They had just come off the delivery truck. On Monday, we thought we'd like a couple more. So we went back to the nursery. They'd sold out already, in just 3 days. How clever of the nursery to get fresh supplies delivered exactly in time for weekend sales. And the message for we retired people is - buy up big on Friday!
