Mancini Racing Shipping Charges?

I ordered a cast crank from an ebay shop, $149...shipped! Shipping a crank is expensive but these guys still turn a profit. I get stuff all the time in those mylar bubble wrap "e-packs" and the rate on those is pretty cheap. Why box and bubble wrap spark plug wires? ****, I get electronics stuff from China for $2, and that includes shipping! I always try and set a shipped cost when I sell something, no stress on the buyer. Just plan ahead. Be aware on Rockauto.com. Although the prices are very hard to beat, their shipping adds up on multiple items. The 1.99 wiper blades advertised turn out to be about $10 after shipping, and thats close to Autozone price.
