It is a hit and miss affair for me. We got conch shells in VX - Margarita island - no problem bringing them back - in STT, I had two and they would not let me bring them in. They kept them. I regularly bring back a few small bags of small shells from AXA, no questions, I had one big conch shell last year and they let me keep it. I hope when I unpack at home that they are there, but if they are not, I will try again next year. There are not that many big shells on the beaches of Anguilla, so anything is a real find.
