What to buy:
Don't forget to try Coron's "Ballpen pusit" (Php100/pack). Very delicious and tasty, especially when dipped in vinegar with garlic and pepper. Also try their Danggit. Kinda unique, not like your usual dried ones, but soft and marinated well (Php 300/kilo at The Village Lodge but others sell it at a lesser price. I just cannot vouch for the quality because Village Lodge's tastes very good!
Not much Coron souvenirs can be bought. The t-shirts I found (selling at Php 140-Php 180 depending on the color and size) are limited.
