Such German "Leckerbissen" aren't available "ALDI Jahre", so when we discovered red cabbage and white asparagus and "Bockwurst" and "Leberwurst" during this week's visit to ALDI, we didn't hesitate to stock up for weeks, if not months ahead.
I just thought you'd like to know 😀
P.S. Yes, you're right, there's a comma missing between 'months' and 'ahead', but inserting it would've forced 'ahead' onto the next line all by itself. It came down to a choice between punctuation and lay-out.
