I am trying to order a bubble clip for a Gorillapod SLR, to a US address, but I don't see an option for free shipping. These are my only options:

FedEx Ground® (USA Only) – $4.80
USA - FedEx 2Day® – $14.87
USA - FedEx Std Overnight® – $24.17
Fedex,CANADA only,no GST incl. – $13.00
Intn'l Mail (Accessories ONLY) – $3.00
Intn'l Priority-no VAT incl. – $20.00
US Mail (Accessories ONLY) – $2.00

Is there a restriction on accessories in regard to free shipping? I didn't see this in your shipping policy: "We offer FREE ground shipping on all Gorillapod orders to customers in the continental United States."
