love second hand toys! I do buy new but my kids are used to getting toys from thrift stores. especially going out with grandma! It is amazing how many new or nearly new things you can get.
most things like the melissa and doug puzzles are way too pricey new. I have gotten so many things used and unique things too. My mom just got a wooden thomas the train set in the box... blowing down the trees set, with thomas and james engines for $6 at sally ann in the box. had been played with but just a little. someone there did not know the price of thomas stuff! I told my mom what a deal. the box had the sale price of $39.99.
part of the kids xmas gift is a pokemon fiqures set I got from craigslist for $30 better then the $100 it would be new.
