I guess "getting into Christmas" probably means something different to everyone. For me it's about reliving good memories of friends and family. Some of my favorite memories are decorating cookies with my kids, mixing batches fudge, sipping eggnog and coffee over pie and ice cream, or dancing with my kids to Christmas music.
So for Christmas I play Christmas music, setup a tree, make cookies and fudge, and send the treats and little mementos to friends and family around the country. This year I sent Christmas muffins, fudge, drawings my daughter made, little $1 bottles of peppermint schnapps with Cocoa packets, and other things like Santa socks that I divied up from a cheap multipack. That was the presents I sent out to all our friends and family.
But if I didn't have those memories or enjoy baking, I doubt I would do much for it. So I suppose, ask yourself what getting into Christmas means to you, or take the time to define what you want it to mean to you, and then do the thing. If it's taking a little bit of extra time to show family you are thinking of them, then a little home assembled Cocoa kit and a card might do it. You don't need to go crazy with decorations or buying presents to get into Christmas, unless that is what you want it to mean to you.
