OK so I know these have been done to death, but just in case anybody fancies it, here's a code to get you a free box of healthy snacks delivered to your door, then 2nd box half price. J9Q12KQN I get a pound off if you use this code.
They go back up to 2.99 after that, but you can then cancel. I had some lovely spicy crackers, dried cherries, chocolate etc today. You can rate food on their website to state your preferences, but it is mostly stuff like nuts, seeds, dried fruit, little bit of choc, olives etc.
