Im trying to find better prices for car parts especially filters (air filter, oil filter and cabin filters for my Ford Focus 2004). The average brick n motar stores such as Supercheap, Autobarn and Repco are overpriced are finding other alternatives to make purcahses.
Thanks.
sparesbox is worth a look. Plus there was an amex offer a month or so ago, where their price on a part was already 20% lower than anyone else I could find, and I got another $50 amex credit back. They also have an ebay store which is sometimes part of 20% off deals, so compare that (all ebay sellers for your parts) as well.
That said, the stores you've listed would sell oil filters for $20 or less for your car, not sure how cheap you think you can get one.
