It would be better if they also accepted bitcoin, but still, that's a good start.

BitoEX CEO Mr. Cheng Kuang Tai said, “Following the existing 3000+ FamilyMart convenience stores, BitoEX has signed agreements with two other mega convenience store enterprises (OK Mart and Hi-Life), making it now a total number of more than 5,000 locations in Taiwan available for purchasing bitcoins in late 2014. We have chartered KBBEX as our supplier of Bitcoin to BitoEX. We are confident that in collaboration with KBBEX and the associated companies, the recognition of bitcoins will grow and general public would cast their vote of trust to bitcoins.”
The quoted article has been published today, but it mentions "late 2014" so not sure whether it has already happened.
