Can I make changes to an existing address?

Yes, but only to shipping addresses. First go to My Account, then follow these steps.

1. Sign in, click on Account, Profile.
2. Under Shipping & billing, find the shipping address you want to change and click the edit button.
3. Make your address changes within the open/editable fields. Any fields that do not show as editable are read-only. To change read-only information, select Add new address.

- Attention Line
- Nickname
- Department or lab
- Building or room

*Please use a valid company or institution address. We are unable to ship to apartments, P.O. boxes, or personal addresses.

During Checkout you also can Edit the above fields on an existing shipping address for that current order. You also can save changes to your Account Section.
