COVID 19 update. Overseas shipping is now with a courier only. UPS or Parcel force.
Orders placed in the afternoon normally get sent the next workday where possible. Orders placed before noon are often sent the same day but this is not guaranteed. Priority is given to Royal Mail Special delivery items always.
Same day disptach is not guaranteed due to volume of mail order. In general we are not operating with big delays in dispatch if any.
- Standard shipping is with Royal Mail using there 24 service. Cost £3. This is not a guaranteed service and takes 1-7 days normally but can be longer. The tracking number is not tracking but is a conformation of delivery code. If the item has been delivered to you or a neighbour then the tracking shows something otherwise it won't. If the item is needed urgently then pay for the courier/special delivery. in the case of the items recorded as delivered but you claim non delivery or delivery attempted but parcel never available for collection no refund or replacement goods are possible. R24 is not a tracked or insured service. We are only liable if delivery never happens. We wait 30 days before declaring am item lost. If this is not acceptable to you then pay for Special Delivery which is tracked and insured. We are not longer taking the hit for lost items because you want to spend less on postage.
- For a £7 surcharge, a next day (not sunday) tracked service (from dispatch) with Royal mail special delivery is used. You get an hour delivery slot by text. It's a fine service and worth the money. This only works for items up to 2kg. beyond that it gets very expensive and Parcel Force 24 tracked is used. This is fully insured service so in the event of non delivery a claim is possible.
- Rims are sent by courier only- cost £10. UPS is used. A phone number and email address must be supplied to allow me to book in. This service can also be picked for smaller items that you want delivered by UPS.
- Wheels shipping cost is £15 (cost of courier + cost of the box) next day. To NI, Scottish Islands, Channel Islands, Isle of Man and that is a two day service.
Due to the disruption in postal services during 2020, misdeliveries, customs issues and long delays all overseas shipping is now with Royal Mail Internation al Tracked and Signed (europe only) and UPS or Parcel Force tracked services. Parcel mass and destination affect price. So the following applies. I do not offer cheaper slower mail services anymore. Please don't ask as it means you have not read this page. There is no circumstance where i will use a cheaper service.
