Has anyone actually received an amazon prime item in the 'guaranteed' 2 days? My last 5 orders have not. Is this typical?

Yes but the neither of the two items I ordered are going to be here by the "2 day promise".

I have... in fact, I've received next day for free with prime.

Most of my orders have arrived in the “guaranteed“ time frame, but some haven’t, so it’s not really a guarantee and they should change their wording to be more accurate.

Most of the items i have gotten were 2 days. I only had one item and it was my ear stretching kit to put big holes in my ears like cool kids. It got here on tuesday and i ordered it friday night. this was just like week ago. out of everything i ordered it was only that

The vast majority of my orders arrive in 2 days. It is pretty rare that it takes 3 days.
