Maybe I haven't visited the right ones, but none of the 7-Eleven (or FamilyMart, Lawson, OKmart, or CU) stores I visited in South Korea, Taiwan, or Japan had selections that close to those of the Dollar General stores I've patronized. In my subjective judgement, the difference is pretty big. This is not a knock on them, of course, just difference in business model, and as you say, regional/market context.
