DD (6) seems to enjoy Magic Tree House books right now. Her teacher reads a chapter a day and they are on book 4 or 5 already. I am thinking about getting her the series (or at least the first half of the series) for Christmas. Suggestions on how to do this? I can get them through Scholastic for maybe the best price (if you factor in the 'new book' thing too). Or I can buy smaller lots from Ebay, maybe cheaper. Or I can keep checking the thrift shops near us, definitely cheaper but not new but that is not really a huge deal. Or I can tell everyone that will buy for her that she is collecting these books but then I have to deal with constantly updating which she has and figuring out what to do with multiples. She hasn't specifically asked for these, I'm just hoping she will want to read them again at some point. Suggestions on best way to buy them?
