@kovidgoyal: That is what I thought. Thank you for the confirmation again.
@davidfor: Thanks for your suggestion. It looks like the
Import List Plugin may resolve the issue, however there are some possible problems as well.
- CSV File: Amazon US does have a feature called "Order History Report" where you can export the data. Unfortunately I use Amazon Australia and Japan and they don't have this feature. If I use this link HERE or other methods, I can extract the data, but the price information doesn't seem to be included. iBooks also doesn't have a feature like this. I could maybe use Automator to automate and extract information from receipts but that could take a while and maybe not worth it. The majority of my books are in iBooks. If you can think of another easy way of getting this information, please let me know.
- Import from Webpage: This could potentially solve my problem if it can extract the price information. Although the price that I bought compared to current price may be different, so this may not be possible. I may need to play around with this feature more. Please let me know if you can get it to work. I think the CSV method would be the easiest/best method.
