Today I received an email from zipzoomfly.com that reads:
We have check our inventory in regards to your situation and have not found any discrepancies on your items. For this reason, we will not be able to reship the parts out to you. Please feel free to contact us if you need anything else.

Excuse me? That's it? I bought items, the items didn't arrive, and you just don't care because your inventory all matches up?
I think I'll be calling my credit card company this evening.
Edited to add: I called FedEx about a claim - they said that the shipper usually initiates the claim process, and were kind of surprised that I was the one calling them. However, they've scheduled someone to come out tomorrow to inspect the shipping cartons (and hopefully they'll make it in the window I gave them, when I won't be at work) and they'll investigate the claim. At least someone's willing to help me out.
