The process of searching iTunes Store purchase history is REALLY awkward. It seems designed to discourage customer inquiry or use.
See below a brief list of steps (seriously) I just worked through in order to save my 2014 iTunes Store purchase history:
- Log into iTunes Store account
- Navigate to Purchase History
- Press Command-Shift-4 and select a screen capture of the list showing a few recent purchases
- Click Previous or Next button (To see earlier purchases click Next, click Previous button to see later purchases. Really.)
- Press Command-Shift-4 and select a screen capture of the resulting list
- Repeat (8 times) until desired lists have been captured as screen shots (or until you walk away in disgust)
- Then open all .png screen capture image files in Preview
- Export all image files to .pdf
- Open newly exported .pdfs
- Combine .pdfs into one file (see Preview Help for this)
- Click and drag .pdfs into a coherent order (suggest chronological order, but coherence is optional)
- Save As... your combined .pdf to a location of your choosing (printing optional)
- Log out of iTunes Store
I hope this was helpful for everyone. Have a swell day 😕
