Sales are not very successful here, esp. if you are trying to use sales to boost how many items are bought. If you want a sale to be successful, they need to be planned months in advance so that you can promote them. I did a one day sale in July, and had promoted it on my Facebook page for a month before it actually happened. I announced it a month before hand with little details, then gave bits of the details little by little as the date got closer. In that once day I got 4 sales, 3 being big ticket items. Every other sale I have done has never worked.
