@mastiffrex :
Best care scenario is 3 days, average is one week. Worst case is one month, like for large items, with the frustration been that they don't ship immediately, but like 2 or 3 weeks later.
The best case scenario is for items shipped from Seattle and ordered on a Monday or Tuesday. If I order on a Wednesday that means Saturday delivery, which typically comes in at 8 or 9 PM and there is a high chance that there will be a "delay" and delivered at the "next opportunity" which means the following Monday or Tuesday.
Most Prime deliveries are by USPS; I rarely get stuff on UPS or Fedex, as their rates to AK are similar to a foreign country.
I used to buy all supplies on AMZN, but now it's best just to go to Fred Meyer's (Kroger's) down the street. I get to put three layers of clothing, get on the icy roads and put on a face covering, just to get coffee.
