You can either
1 - get a 40 GBP CHarles Tyrwhitt Voucher from Groupon for 20 GBP which you can then apply to their shirts (many 70-80 GBP shirts are currently on sale for between 15-20 GBP
Site : http://www.ctshirts.co.uk/default.aspx?q=gbpdefault|||||||||||||||
Postage will be 15.95 to Australia which makes 2 (20 GBP Each) shirts (via Groupon Voucher) about $67 delivered.
OR 2 - Go direct to their Australia site (http://ctshirts.com.au/lep6) for shirts for 30-40 AUD (looks to be double the GBP price, so equivalent to the 15-20 GBP shirts) or 2 for (60-80 AUD) - shipping is free
Cheaper to go for the Australia site if you just want one of the shirts or want the $30 (15 GBP shirts). Whereas if you want the 10 GBPO (40 AUD shirts), the groupon, UK site + delivery option is better
I've been wanting for a reason to try these guys, Thanks!
Edit: nvm.. just realized it is through groupon….
