You should definitely wait until you are here in the U.S. How much duty free can you take back into the U.K. with you? I just checked Joann.com international shipping & handling and it says "unavailable"; I don't know if it's the s & h that's unavailable or the information. Either way, it'd be best to get your stuff here. I get all my cutting supplies at 40% or 50% off at Joann's, either on sale or with a coupon.
