I'm very pleased at how much I've been able to save with 'experienced' uniform parts. Thanks to my folks passing along three short-sleeve uniform shirts my brother had outgrown ($24 apiece new) and scoring a pair of gently worn shorts and an unhemmed pair of trousers in separate eBay auctions for $25 plus shipping (just under $70 new), all I've had to buy new are insignia (~$10 per shirt), a neckerchief and a Scout belt ($6 each).
I still need to buy a few small items -- a council shoulder patch for each shirt, shoulder tabs or 2" wide grosgrain ribbon to make them myself, and my position insignia -- and the appropriate colors of thread to sew on a few patches and hem my uniform pants, but I've gotten squared away with an entire uniform for less than I would have paid for one new shirt with insignia and a pair of pants.
Today's moment of Zen: complete your Playmobil airport play set with a security check-in. Marvel at the working conveyor-belt action!
