Marketon is my favorite place to buy inexpensive produce, pastries (especially Conchas and Pan de Muertos) and occasionally canned fruit that I can't find anywhere else but that looks enticing.
Every week I check the ad for their Wednesday and Thursday specials which have fruit, veggies and sometimes bulk beans. They also have Friday and Saturday specials, but those tend to be meat heavy and I don't eat meat. The price for sale produce is lower than most other stores.
The parking lot is spacious, and the store itself is clean and well lit. I appreciate the wide aisles and never have a problem navigating my cart of goodies. The cashiers are very friendly and tolerate my noob Spanish language skills. I also like the free Spanish publications near the entrance, as they are good reading material to improve said noob level Spanish.
