I'm not sure I'd buy spices to transport back. You'll want to know customs rules for the specific spice and source as there are sometimes plant diseases they're trying to quarantine.
My sister, well-meaning, has brought back spices for me from her travels. The ones she encounters at least are set up for the tourist to bring back, but are often inaccurately labeled, have fillers or other questionable quality. A good spice vendor in your home country will probably have spices as good as what you can bring back unless you have a special source you're visiting such as a specific grower or such.
I'd be more inclined to make connections for ordering directly later, say from an artisan olive grower for oil or similar.
