Packaging & transit

We pack every order carefully, but some products are fragile in parcel transit. We cannot replace or refund cans for cosmetic dents, or Pringles and stacking crisps where chips have broken during transit.

Damaged or undrinkable? If a can arrives undrinkable, please contact us and we'll be happy to help.
