Me and DH buy presents together, so ...
DH, Myself, My Parents, His Mum, My Brother, His Brother, My 2 Grandmothers, My grandfather, My Aunt, My Uncle, My 2 Cousins
The rest of the family I don't see a lot, so don't buy anything for (same goes the other way around). My BIL doesn't tend to get a lot as we don't get along too well, my parents never use any of their presents so aren't fun to buy for, my brother is spoiled rotten and hard to buy for, my aunt/uncle & grandmother get small and home made things and my cousins are fun! =D
I'm not keen on the buying presents bit apart from buying for my MIL who loves anything she gets. Next year however, we can buy for our own little one! Woo-Hoo!
