Set your Buyer requirements to block customers in locations you don't ship to.
This does not stop international customers, who have a USA shipping address. These customers may be shipping to a relative in the states. Most commonly, they are using one of the many freight forwarding companies. Delaware is popular because there is no sales tax there.
Once a listing is sold, the seller is obligated to follow through with shipping when payment is received. There is no declining a Buy It Now. If you cancel a paid item, you get a defect (and I don't think the Final Value Fees are not credited back to you). The customer can also leave negative feedback.
Please read the eBay Money Back Guarantee as well as these boards to help you understand the difference between your 'no returns' policy and the MBG.
I've been on eBay for 15+ years and I never list anything I can't afford to give away. My business model limits me to listings below $150.
