Christmas is only around the corner...

Ok I'm starting to freak a little, Christmas is exactly a month tomorrow and I haven't even brought on present yet, I sort of know what I'm getting for my sister but no completely sure, but other than that I have no idea. Like what am I suppose to get my little brother, my mum? Like seriously and then there's when am I going to have time to go get the presents but mainly where is the money going to come from, I know that I work two shifts a week so I'm earning between 50-60 pounds but I don't have the time to work and other time, so it looks like I'm going to have to stay in, stop spending my money and save for a 2 more weeks so I have about 200 saved and then hit the shops and get my dad to take me.
People give me ideas for what I can buy for my sister she is 14 or my brother who is 4 or my mum. I need help guys!?!

PS. Here's a picture from my way back from work there was about 150 birds flying in a pack, it was beautiful.
