Accessible black friday apps?

Hello all Since there is a huge amount of black friday online deals this year, it is sometimes quite hard to sort through them all using various e-mails and websites etc. Does anyone know of any accessible black friday apps that list adds/deals from various stores? Just a listing would be fine, although I'm sure these apps let you sort by category, set notifications and open a deals page in safari to let you purchase something. I have seen at least 5 so far on the app store that are free but don't have time to test them at the moment. Thanks for any suggestions and also for the excelent work that the apple vis team does.
