International Orders:
We offer shipping to international locations but not all countries and products are supported. Generally, if you are an international customer and you can select your country and address at checkout, it means we can ship that product to you.

We do not accept returns on electrical products, but may offer exchange / refund on other parts. The parts must not be used, damaged, or opened (on parts in packaging) and will be subject to restocking fees of 20% (depending on the part). This fee applies to all returns.
If you have received a faulty or damaged product, we will always offer a replacement (or refund depending on availability) at no cost to you.
Backorder Items:
As there are 100,000+ different SKUs we are able to source, we are unfortunately not able to stock all the parts that customers may need. Many parts will have to be ordered in from their respective suppliers and have varying lead times depending on the brand and part. For most parts, this is about 2 - 7 working days, however for some international brands or parts which are on backorder, there can be an extended lead time of 2 - 12+ weeks. If you are not happy to wait for your order, please get in touch with us and we can give you an ETA or cancel/refund your order for you right away.
