In Yilan there’s only one Carrefour. In the past they had the same veggies and fruit as Px Mart and Surewell, but they also had a lot of imported stuff. We always preferred to buy that kind of stuff in traditional markets, but on days during which we were a bit short of time it was ok to buy veg/fruits in Carrefour. Over the last two or three years they basically cut the veg area in half and now they have 75% of stuff on display labeled as “organic”, which is a huge NOPE for the wallet. Basically we now only go to Carrefour for the Atoha food/wine because the selection is much better than other stores in Yilan (no Costco here, sigh).
Newer PX Marts in Yilan are pretty good, they’ve been building a lot in recent years. Going to Taipei by bus and arriving in Technology Building station always makes me feel at home with 3 PX Marts within 200 meters or so.
