I've had 13 Amazon orders this year and I got them all within a few days of ordering them. Just mentioning since threads like this get dominated by people experiencing problems and want to point out it isn't always like that.
Also throwing in my data point: Very consistent for me as of late. I've had issues in the past, but most of those were nearing a decade ago. Amazon is probably the best delivery service I use on a day to day basis, with FedEx being the worst in the last few years for me, anecdotally.
