Step 1: Buy LEGO Set 8014 - Clone Walker Battle Packs
Now, don't panic, we will be recouping some of your money.
Step 2: Seperate Your Clone Troopers From Your Clone Walkers
Step 3: Sell All Clone Walkers on Ebay
TIP: Don't overcharge for shipping, nobody will bid on your auction if the shipping is unreasonable. For this $2 max for shipping. Also, end your auctions on weekend nights, that's when most people are shopping for this stuff.
Typically, from my experience you can sell each clone walker anywhere from $3 - $5 each on Ebay. After you've sold these you'll recoup about $30 - $50 of your initial $110.
