Technically, cash-back offers on TopCashback.com and its associated apps/extensions are only available to residents of the United States. However, the company’s website says that TopCashback users from Canada and Mexico may be able to utilize the site — though cash-back is not guaranteed in these cases. Residents of the United Kingdom must use TCB’s UK cashback portal, which can be found at https://www.topcashback.co.uk/. The company also has dedicated sites for China, Germany and Japan.
