Who is Snip not for?
If you're someone who does all their grocery shopping online, then Snip might not be for you as only ASDA, Sainsbury's and Waitrose are available for online shopping. Sainsbury's also has a spend limit of £250 per shop, but the Waitrose and ASDA don't have a limit.
However, it's not just supermarket savings that Snip gives you access to. If you're a shopaholic, or are planning to make a big purchase such as home appliances or furniture, Snip could help you save in that way instead.
