If you’re in North America, go to the US Store.
If you’re in the UK or Europe, go to the UK Store.
For other countries, my advice is check both stores, and here’s why: the shipping costs and delivery estimates vary and the only way to be 100% sure what’s the best solution for you is to quickly check them both, like you would Amazon.com and Amazon.co.uk.
If you’re not sure which is best for you, just message me. Click the “Contact” button in the menu bar and get ahold of me, and I’ll help you directly. Rule of thumb though: if you order from the UK Store, shipping is a bit more expensive but the delivery will be quicker. The opposite is true for the US Store: cheaper shipping, but will also take longer. Remember, like I mentioned in the above question, you can check a shipping cost list for the US Store and the UK Store.
Or contact me directly. I’m an easy-going guy. Unless Cena wins.
