Yes! Relentless Improvement Ships Internationally!
In fact, every day. Common destinations include UK, Canada and Australia. No problems, ever, so you can order with confidence.
Please keep in mind delivery time is wholly dependent on customs clearance at the destination country. Some orders deliver in 2-3 days, others get caught in a customs backlog and can take up to three weeks. It can't be changed or sped up, it is just a necessary evil with international shipments. The good news is that orders always do show up and I've never had a report that there was a delivery refusal or any red tape.
