I always thought 4 days was pretty fast considering they sort your package into the pile heading for your state at the sorting facility, they ship your package across the country in a cargo plane, unload it, sort it, all this sht. Its not just the act of doing all this, but they have to pay every hand it passes through, the rocket fuel for the planes, the gas for the mail trucks. I mean I always thought it was a pretty amazing feat that for 2.50 they get a package with one bottle of juice across a country & to your door in 3 to 4 days. I live on the east coast, and it doesn't matter if I order from the east coast, or california, I usually get everything in 3 days. When it takes 4 days, I get disappointed, because I always go to the mailbox on the 3rd day excited for my package. But sometimes it does take 4. 5 days is just unheard of. I think thats a pretty cool feat that our nation has going for it considering 60 years ago everything traveled by train. & the entire bible belt relied on mail order catalogs for everything from their clothing to some of their important medicines. and 100-110 years ago you relied on horse and buggy and it took 2, 3 weeks to get that new dress for your annual yearly family portrait. Now thats how long we wait for a bottle of juice to come from china.
I think you might be missing the op's point. If it's going to take 5-10 days and they say that up front no problem. I'll plan for that. It's frustrating when you pay extra for 2-3 days service don't get it in 5.
If you ordered pizza from the from a place advertises 20 minute delivery but it really takes 2-3 hours would you not be a bit ticked?
