Depending on what you paid it's going to be around £100 (I was the $450 tier but had a 10% discount). The 2 part shipment might stuff that up though, will depend on what the values on the boxes say. The handling fee from FedEx is some percentage I can't recall, minimum £12 which is what I used when I worked it out. Sounds like they invoice you rather than hold the package which is a small mercy.
