That might be the way to go but it will depend on what you are buying. I found the Olds diesel pan gasket and intake gaskets on clearance for half of what summit is selling them for but both come from warehouse D, maybe the clearance warehouse? They are considerably cheaper than Summit and carry more brands for rebuilder parts.
I run every part# through Amazon, for comparison. If it's STOCKED and SHIPPED through Amazon, it's almost always cheaper than the competition. Here's the deal... You, and Me, can sell on Amazon, as 3rd party sellers. My price on VR1 oil, is NOT going to be as cheap as Amazon's, and MY oil will not qualify for Prime's " free shipping ", because I'm a 3rd party seller. So any item that is STOCKED and SHIPPED through Amazon will qualify for Prime's free shipping. Almost guaranteed to be cheapest option. I am a Prime member. Now, add in my Amazon Employee discount, and I got the upper hand on ALOT of purchases. I'm also a huge JEGS supporter. They carry items that Amazon does not. They send me MANY discount offers. They also " price match ", and offer free shipping over $99. So, I wait until I have $99 worth of stuff in " My Cart " and then use my discount offer, and as most of you know... That's how I do it. So as stated above, in a previous post, do the math, Google your part #'s, and you may be surprised how far you can stretch that dollar. I'll end this on a Positive note for Rock Auto... they sell Mopar parts. So that water pump I needed for my Hemi Ram, was $220 at the dealer. NOT!! I started looking around... the same Mopar part # on Rock Auto was $140 = SOLD.
