It'd be easier if you have Paypal, or a direct Debit/Credit card handy.
If you own any of the above, its simply the task of adding things to your 'cart' through the theory 11 product section. (Tricks, playing cards, 1 on 1 and gear, which all have respective tabs just up the top)
Hey Vogue and welcome! Well I am sorry, but because you live out of the US, you will have a large shipping charge. There is no avoiding it. I'm sorry. You could always search for magic stores online or in person near where you live though and see if they have the products you want. On Theory 11 though, many DVD's are actually offered as downloads so you can just download the DVD from here without having to pay for shipping. Sadly you can't download a deck of cards though.
Hope that helps! PM me if you need further assistance. I'd be happy to help.
