It is not critical if you don't know some of the details. The essential details that are required are marked with an asterisk (*). If you are having problems finding some information then just fill in the form to the best of your knowledge and submit it. One tip for finding the shipping weight is look on Amazon as they normally include the shipping weight on most items.
If you are still unsure of the shipping weight try using my shipping cost calculator and/or select the "estimate shipping for me" option from the international shipping drop down list. We will provide you with an estimate of the shipping cost in the final quote email. If you have an approximate idea of the shipping weight it is a very good idea to choose the appropriate shipping weight. Don't worry about being overcharged if you estimate too high since in the end you are only ever charged the actual shipping and handling cost.
The most important thing to do is to provide us with enough detail so that my USA partner knows what you want without any possible confusion. It is critical that you include a description of each item, the direct weblink (url) to each item, the price of each item, and any other information required (i.e. size, colour, number, etc). Not including this required information will mean that we will have to contact you before we can send you a quote and this will only delay the processing of your order.
My USA partners are all located in Oregon (OR). You may need this information to estimate what USA shipping will be applied. If you need a USA address to work out the shipping then please use the USA Test Address.
