Dollar-stores overcharge customers while promising low prices

I experienced this first hand maybe a year ago when I randomly walked into a dollar general to get something, their prices often times are pretty close to the "regular" versions of the product, but packaged specifically for dollar stores.

I get why people shop at them in rural places because that's the only shop within 10-20 miles but in cities it makes no sense. Had prices been 20-30% cheaper but in a smaller size it would still be a ripoff but an understandable one, but often times I saw products that were priced just 3-5% below their standard counterparts while giving you maybe 30%-50% of the product.

Same. My city has a Walmart, Publix, Food Lion, Kroger, and Aldi. Yet they keep building dollar stores, I think there's now 5 within 10 miles of my house. They all seem to do decent traffic, which baffles me. The stores are a mess, items disheveled everywhere, and rare to see more than a single person working. Really depressing places, I cannot figure out their appeal.
