Conditions per usual
Discount applies to full retail price and cannot be used in conjunction with any other offer or discount, including catalogue lines. Discount does not apply to purchases of transmissions, satellite navigation devices, automotive, marine & deep cycle batteries, engines & cylinder heads, equipment, gift cards, any trade purchases and Trade Workshop Equipment. Store Stock only. Discount does not apply to purchases from the Repco Authorised Service network.
With them having an actual e-commerce website you can also compare prices easily now without heading in so makes this 30 % off deals a lot more user-friendly. Always best comparing their prices before pulling the pin as sometimes there RRP means that even with 30% off its no deal.
According to the OzBargain discount eGift Card page you can get 2% off Repco eGift Cards from Blatchys Blues which I assume would stack (but haven't tried), might be worth it for big purchases.
