Amazon vs Donki for souvenirs/snacks before going back home?

Hey everyone,

I’m going back home for a few weeks soon (first time since coming to Japan a little more than a year ago), and I’m trying to buy some souvenirs/gifts for family and friends.

Mainly stuff like:
Japanese KitKats (matcha, strawberry etc)
chocolates / sweets / snacks
maybe some Japanese stationery
also thinking of buying a few formal shirts
(something made locally / good quality)

I live in rural Shikoku, so the nearest Don Quijote is like 1.5 hours away by train + a lot of walking, so it’s not exactly a quick trip.
But I don’t mind going if it’s actually worth it.

So I wanted to ask:
Is Donki still the best place for snacks/souvenirs or is Amazon just easier now?

Any suggestions for good “Japan-only” items that people actually like receiving?
