I was in the market for some headlights earlier today and came across this site - plenty of decent reviews online and they seem to even post here every now and then (I'll hopefully beat them to the punch this time).
Thankfully I didn't purchase earlier today because they just seem to have started a 20% off everything sale. Their prices were already highly competitive and now are even cheaper.
For instance, the Philips Longlife EcoVision H7 Headlight Bulbs (Twin Pack) that I was looking at came down to $26.18, whilst a SINGLE bulb at the ironically named SuperCheap Auto costs $29.99.
Enjoy!
They forever have a 20% sale, I'm patiently waiting for their 25%-30% sale myself here instead lol.
