if it's coming via UPS Surepost, my experience has been about 23 days, +/-.
if it's coming via Fedex Smartpost my experience has been about 40 days, +/-.
the bad thing with Fedex Smartpost is that the tracking status shows "label created, waiting for package", even though it's on-board a truck zig-zagging across the US. Apparently, the shipper is able to see actual status, we as peasants do not see those updates.
Midway uses UPS Mail Innovations, that takes about 8 days, +/-.
you really don't want to go with a USPS "low-cost" choice, that would be Parcel Post. and on that one, the package does get beat to shit. I've had empty torn boxes arrive. I've seen that vary with 4 days to 40 days.
this is one of the hidden costs of "living in paradise", the high cost of living in Hawaii. At least with some vendors, you can step up and pay more (out of your own pocket) for Priority Mail, or UPS/Fedex 2nd Day Air, or, get used to it, deal with it, or move. your choices. 'murica!
I'll bet the folks in Guam, it sucks even more.
