*Please note that any other items ordered with food will be sent separately via Royal Mail 2nd Class by default. If you require non-food items on a faster service we offer the option to upgrade to Royal Mail 1st Class or Courier delivery of non-food items for an additional charge.

For more information, view our delivery page.

If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.

We had moved and I forgot to update our change of address so my order went to the old address. After my phone call to them asking why I had not received my goods they phoned me back saying my parcel was back with them and would immediately be sent to the new address. The next day my goods arrived. Customer Service was excellent.


As usual good service and great prices.


Great service with prompt delivery and value for money
