Sow the seed

I bought a new pair of running shoes a few days ago and the sales assistant used a very clever trick when describing a new pair of socks.

I've got socks - lots of socks! Why would I want another pair?

Apparently these socks had special moisture wicking properties and additional cushioning technology.

When I was out running a long run, I remembered what he said & with my damp, sore feet thought these new socks could be just what I "need".

By sowing this seed (new socks), allowing it to germinate (me thinking about it), he will be able to reap the harvest (when I buy them).

What seeds can you be sowing with your customers to upsell your product or service?
