Does anyone know of any Car boot sales this weekend on the North Coast?
You looking to buy or sell?
There used to be a flea market every Saturday in East Cabarete. Not sure if it's still running though, perhaps someone else can confirm. Perla Marina occasionally hold a car boot sale.
But if you're selling, I would suggest you join one of the Facebook pages dedicated to buying/selling second hand stuff. They are called "Everything Sosua", "Everything Cabarete" and "Everything Puerto Plata" it's free to publish an advert.
