What to pack vs buy locally for a more sustainable or lighter trip?

Bring items that are hard to find or that you have specific preferences for (good hiking shoes, specific medications, high-quality sunscreen, insect repellent you trust, any specialty gear). Many everyday items are available locally and often cheaper — toiletries, basic clothing, snacks, and some outdoor gear. Buying locally supports the economy and reduces what you have to carry. Reusable items (water bottle, shopping bag, utensils) are worth bringing to reduce single-use plastic. Some travelers bring a small medical kit with familiar items. The key is distinguishing between 'nice to have' and 'essential.' Many people overpack and end up buying duplicates or carrying unnecessary weight. Local pharmacies and supermarkets stock most common needs.
