Where could someone find cheap bras that are made to wear for backless dresses?

Cheap Bras for backless dresses can be found on sites like eBay (not always used - occasionally there are used bras listed but some people find that idea disgusting for whatever reason), Very or Asos. Debenhams also offer bras for backless dresses for affordable prices and there is a shop locator on their website if you are not aware of a convenient one in your surrounding area. Supermarktets are commonly overlooked for clothing, but ASDA's George range and Tesco both offer bras for backless dresses.
