Ha, you sound like me - we've only bought a mattress, pram, cloth nappies and babybjorn active. Everything else has been given or was off freecycle.
I got a Babyco beema jogger pram thing from ebay for $60 and then another as a surprise gift for a friend who was using ours until the birth ($80).......considering they retail for $400 or something, ebay is always worth considering! Just remember to check out the sellers rating!
