I constantly buy diodes, resistors, etc. for projects and i mostly save the receipts. I want to know if there is an org-mode way (or any other software) that let's me input all the data form the receipts and tell me which components are cheaper in X store. A plus if it has a way of telling me how many components i have left. Thanks in advance. NOTE: Since i don't know what name this kind of software receives i have not been able to find what i look for, so excuse my ignorance
