Payments & Returns

So, how do I pay for my order?

  • You can pay by Visa, Mastercard, Laser, American Express and almost all other popular cards. Our online payments are handled by Realex, one of the worlds most secure payment providers. Your card details are secure throughout the whole transaction.
  • You can pay by PayPal at checkout also.
  • We also accept cheque and postal order. If you decide to go with this payment please make it payable to 'Allmoto'. On of the snags using this payment is we must wait until it clears with our bank and this might delay your order a few days. We'll keep you updates if there is any delay.

So what's the Allmoto returns policy?

Technically, if you have ordered a wrong part, we are entitled to ask you to return it to the Allmoto offices as new, and, we charge you a re-stocking charge….plus the outgoing shipping charge we incurred when we sent you the delivery.

However, in most cases, we try to be sensible about it. If it's an item that we are likely to resell at some point we'll normally just ask you to cover return shipping costs and we'll stock it - however this is at our discretion for parts that we feel that we have some chance of ever selling again.

But I ordered the wrong size/colour/whatever, what do I do?

We must be contacted within 7 days of you receiving your goods. Should you need to return any item please return it with the original packaging and send it recorded delivery. Enclose a returns note stating your name, address and telephone number, give details of the reason for return and what action you wish us to take. 

In the case of faulty goods please contact us on ++353 (0)1 8250703 and we will then decide the best course of action. Any goods returned outside of these conditions will be charged a 15% restocking charge. 

Allmoto are not responsible for any labour charges incurred during fitment or removal of suspected faulty or incorrectly supplied parts. (This does not affect your statutory rights.) 

With special orders or where goods have been made to a customers specification we must reserve the right to refuse cancellation and refunds and the deduction of a handling charge will be made at our discretion.  

Your rights to return goods are protected under the EU Distance Selling Directive which can be found at http://www.hmso.gov.uk/si/si2000/20002334.htm

To explain why we would need a restocking charge on non-stock parts: we (Allmoto) have incurred an incoming shipping charge, a shipping charge to get it to you AND another shipping charge to get it back to the suppliers….after this the supplier will hit us with a restocking charge!


What if I asked for the correct part and you(Allmoto) sent me the wrong one?

Well that's completely different and if this has happened we apologize. We try our best to get the parts right 100% of the time. If we have supplied an incorrect part we fully refund any money including the return postage (and we normally give you some extra discount if we've messed up to keep you a happy customer:) .  


Who do I contact if I have an issue with my returns?

Contact Derek be emailing him directly - derek@allmoto-online.com. You'll also find our main contact details HERE.
