If you travel a lot and have to buy gifts to those back home and if those back home already have EVERYTHING and if you don't always have all the money in the world, buy stuff from grocery stores from foreign places as souveniers. I do that and it works great.
My kids love to get body wash, toothpaste, cookies and candy that are different from those we buy in Finland. Of course most products are multinational and sold everywhere but there are brands of local supermarkets and such cheap stuff to buy.
In Tallinn this October, I bought raspberry jam, tea, crackers, cookies, chocolate and candy. A week later, almost all of it is gone... Gladly, I took some pics at the store.
