My tracking saying the same thing since at least Thrs. Royal Mail sent it, USPS is waiting for it. Is it normal for it to be lost in the ether for 5 days?
Yeah, when it comes to foreign shipping, tracking numbers end up never being close to accurate!! Give it a few days.. Especially an extra day or so w/ Mother's day. All the extra mail may have delayed it a bit. I'm sure you'll get it soon!
