Yes, it's Saturdays and Wednesdays.
The market that Tony refers to by Sun Tropical is very small. He's right... it's not as good.
The telephone number for the Marina itself is +34 928 519 012, and they should be able to help you. Or you can email email@example.com
And of course, like Celtygirl, I want to know what you're selling too! It's a woman thing!
