Yes, it's Naked Wines and yes, their vouchers are everywhere.
Bonus of this one is it's 6 Bottles so you can try it out for cheap.
I'm currently drinking through 15 bottles of theirs and they're more than drinkable, definitely better than a $5 bottle from Dan's. Some unique varieties too.
Make sure you unsubscribe from being an Angel within the first month if you don't want to pay $40 per month.
$5 bottle from Dan's taste much better
