A lot of people complaining about slow sales etc at the moment. Economic uncertainty, holiday credit card bills coming in etc.
Btw, you full business address is not showing up in the listings I looked at - you need to correct that to show your building number, street name and town. Apart from the legalities, buyers tend to hit the 'back' button when they see problems like that. Getting the basics right can be really helpful in generating more sales.
