I checked both of them. I actually need receipts from physical stores like either WalMart, Costco, NewEgg, etc. but not from Amazon.

I see.

Have a look at this thread.

Edit: I downloaded the zip file but it's giving me weird exceptions for both AstroPID and AstroProof. I posted them on the other thread too. Did you face any similar errors? If yes, how did you resolve them? Thanks so much!

It's working fine on my end.

On what OS are you executing the tools?
