We have two web sites under one domain. The one you register under will be the one you use on future visits. European customers will need to choose the United Kingdom, as the UK site will only ship to European countries.
Customers in the United States and other International users need to choose the United States https://www.mscdirect.com/, as the US site will ship to everywhere except Europe.
If you have accidentally registered under the wrong country, send an email to firstname.lastname@example.org and ask to have your registration transferred to the appropriate web site.
