Warning. Zozi is the biggest cashback on all stores, so you can let us know about any store that we don't have the biggest cashback on and we'll fix it! However, right now, the 5,000 ? guarantee only applies to Aliexpress, Yandex Market, M.Video, Eldorado and SberMegaMarket stores, as we don't have the tools ready to monitor the rates on all online stores.
