I like using
Honda Parts at HondaPartsDeals.com: Honda Accessory, Honda Car Parts, Honda Auto Parts, Honda Accord Parts, mainly because they show the actual Honda P/N.
There's also
OEM Car Parts that not many people know about.
A little tip I found, search your local Honda dealers' websites. I found one near my workplace that offers the same online discount as Majestic, but without the ridiculous handling/shipping charges... I am able to stop by on my lunch break and pick them up.
