Like Gigi I make a lot of homemade stuff to give to people and will include something nice from the dollar store for friends, teachers, neighbors, bus drivers, mail & trashmen/women, counselors, pastor & secertaries. My parents, sister &dc's will get the same gift bags but with something a little more to their tastes. DM will be getting a couple old movies on dvd's, dsis & 1 dc will be getting homemade cheese curds, I'm still keeping my eyes open for a gift for the other dc and for df.
For those inside the house other than their annual homemade pj's on Christmas eve I figure out how much I've got total then divde it equally amoung them to find my spending limit, usually about $30 or $40 pp (5 dks, dh, &a family gift). I start 7/25 (Christmas in July) keeping my eyes open and checking out the clearance racks, plus the dollar store near me has an annual 10% off day shortly after Thanksgiving so I grab somethings for them then. I've had some good luck with getting stuff on ebay but you have to start in July and make sure that the seller has an excellent rating.
