Allow changing cashback retailers every 6 or 12 months. Or add them in gradually

Reason being people move home/change jobs and your preferred supermarket may not be in your new area.

Or at least let us choose less than 6 upon signup and add those in later on?

At the moment I’m 100% sure I want to choose Amazon but not so sure about Starbucks/Pret/Nero etc because I have changed jobs (working from home) and in a post covid19 world I may have to work out of an office in an area I’m not familiar with. So locking in retailers that won’t be available nearby my workplace doesn’t look good…
