The thing is unless you pay for Faster shipping. Amazon usually sends their packages via USPS Fedex Smartpost. This means you have to rely on your Post Office to have someone there to unpack the crate the FedEX driver drops off. Some Post offices don't have the manual labor for this and only unload once a week. So keep that in mind. Smartpost isn't the best shipping method although I have to admit to have always gotten my packages on time while living here. I know people who haven't who live in other towns nearby.
Two day shipping is usually through UPS so it's guaranteed to be there on the date scheduled unless something happens.
I'm not sure who one day shipping is through? Probably UPS or FedEX.
