Not really converted. I've been there but Walmart is mostly the go to in Rome. Aside from the two Walmarts and the Aldi there is a Kroger and Publix. The last two are way pricey for me unless I'm looking for something specific.
The Aldi is *really* small. There aren't a lot of choices. As long as I go with the intent of produce, canned goods, cheese, deli style meats, and dairy I'll make it. They don't have diddly for cleaning goods which is okay since I make my own soaps, except for Dawn, and nada for paper goods but those I buy in bulk once a year. Freezer items are good as are chip type snacks.
I eat pretty cheap and simple so in the long haul it will work out.
