Need a shipping label?
We understand that getting a shipping label may not always be easy. Some local retailers may also charge a bit too much for shipping. Just give us a call at (320) 275-9760, and we will be more than happy to build a UPS label for you, and even arrange to have a UPS driver pick up the package at a slightly higher fee. Standard shipping charges apply, 48 contiguous US states only.
