Got an e-mail today from De Long offering 20% off all maps and charts (code BUONVINO).
But interestingly, they also have a cool kickstarter project for a new boxed map set. I have previously purchased their wine region maps that are very good.

I have no relationship with them other than being a satisfied customer.
