That's too bad. There are lots of mitigating factors that can affect sales, many (most?) out of our control. The price of the dollar, the state of the economy, the peace of the nation....But I am also reminded that excuses don't put bread on the table.
If what I'm doing isn't working then I have two choices. Change how I'm selling or change what I'm selling. Neither is easy.
Nobody's buying? Maybe. Sometimes if feels like nobody's selling.
