Download scontrini Esselunga - userscript

Download scontrini Esselunga in massa

Questo userscript aggiunge un bottone per scaricare tutti gli scontrini disponibili nell'area personale di Esselunga.

Lo script si ricorda dei download già effettuati, e li ignora le volte successive.

Funziona solo su browser Chrome-based perché il sito di Esselunga è stato sviluppato poggiando la tastiera sulla sedia e digitando con una penna infilata nell'apertura posteriore.
