So I went into a Family Dollar today and I saw some Transformer stuff. First I saw: Spychangers $2 each Optimus Prime Prowl Jazz Trailbreaker Mirage and Universe toys (i assume are parts of the energon series?) $5 each Arcee Perceptor DoomLock Windrazor Strong Arm Insecticon and a couple more I was just wondering if these were worth buying. I've only collected G1 toys, so any advice??
