Equilter is one of my first ports of call when ordering from Australia - partly because the site is easy to search, and partly because I have always found their shipping excellent. They use Global priority envelopes, pack them as full as possible, and if the estimate they give on my order is not spot on they email me to ask if the increase is OK. I have even had an email that they managed to pack in one less envelope and that the cost would therefore be reduced.
Overseas shipping in GP packs can depend on VOLUME as much as weight. I recently ordered some fleece, and although it didn't weigh much it was not going to fit in a GP pack. I got an email from Paul Rubin asking if it was OK to send by Air Mail.
Absolutely NAYY - just a VERY happy customer.
Some of the places that you all recommend will not ship overseas (understandable for a small business - it can be a PITA) and others insist on using Air Mail or Surface Mail no matter what you ask for. Fabric.com throws everything into one big box (often oversized) and ships airmail - which costs a fortune. Clothilde sends (or used to - haven't checked lately) by surface mail. To me, that takes up to three and a half months and things are far more likely to get damaged. When queried over an order that hadn't turned up after three weeks, I got an email from Clothilde's that said that they never bother to read the comments field on their orders (where I had clearly said I wanted GP shipping). I couldn't believe they would actually write to tell me that! Order did arrive eventually - after over 15 weeks!!
I just wish that all the places that offer free shipping within the States would offer a discount on shipping for overseas buyers sometimes.
