It's also based on the items you're ordering. Some stuff we've ordered arrives within a few days or less. Other items that I've ordered (tools) has taken about 3 weeks to arrive. Some items keep getting pushed back. I would cancel and buy elsewhere but I'd pay a lot in shipping since these aren't all items I can buy from one place online.

I have shopped online for other items though. I bought some insoles for really cheap from a UK based bicycle store, the items got here in less than a week... all the way from the UK! It's not like all shipping is broken down - just Amazon.

Yeah, Amazon has stopped issuing purchase orders for a huge number of non-essentials, which probably contributes to really high delivery estimates. If anything is out of stock at their warehouse, they have no idea when they might have room to restock.

That's the interesting thing. I'm located in a major city with at least one enormous Amazon warehouse nearby. Before the pandemic started we would usually receive our orders the same day.
