South Africa
If you're going with USD or Euros, the exchange rate alone will save you a lot of money. At the time of writing, one South African Rand is equal to seven cents in the United States. Backpackers are hostels/guesthouses/tourist accommodations in South Africa that are often in lovely settings and each has a unique personality, not to mention economical. Food is where the large budget eater or saving may be found, as South Africa can be pricey. Cook your own food to save money. Grocery stores abound and are reasonably priced. You may save a lot of money by preparing your own breakfast and dinner on occasion.
Unfortunately, public transportation outside of Johannesburg and Cape Town is often scarce. While there are a few private firms and railways that provide transportation around the country, renting a car and sharing it with three other people is the best (and possibly cheapest) way to travel around.
