My tip about Christmas is to do with sending Christmas cards. I make a point of sending hand written Christmas cards to my stall holders, suppliers and other supporters. Often I wonder what has possessed me to do this, however I know the recipients appreciate it and it helps grow my business.
The list is constantly growing, so I make sure I get ready early. I either buy them in the Boxing Day sales or buy charity cards. I have a list of people I want to send cards to, and I start writing them about now. Every night I just do a few cards. Writing them this way saves my hand, and it gets them all done. They aren't posted until the start of December at the earliest, usually sent around the second week.
To further save money, I make sure they all have "Card Only" written on them so I can get cheaper postage.
I prefer sending (and receiving) cards in the mail than an email. It's that little bit special.
