I used this to get a little something off about $250 in parts for my MR2. Thanks! Unfortunately the "Mastercard Securecode" checkout widget did not work for me and was pretty frustrating to deal with. I ended up checking out with PayPal, which I think costs the merchant more in fees. I have zero time for talking to banks about crap like this and will probably just avoid using credit cards with Rock. I did send an online message to my bank but have very little hope of them following up in a helpful way.

On the plus side, I compared prices with Amazon and even with paying for shipping with Rock the total was about $75 less. Every single item was more on Amazon than on Rock. "Free Prime shipping" my butt. I pay $100/year so I can pay more for stuff, great.

Used for new rear hubs for SWMBO daily. Thank you!

In reply to dculberson :

Yeah I did the same, Even with priority shipping it was $10 less than amazon before taxes. I went with ground because our postal working is such a POS she won't get out of her truck, and between the music and work, I never hear her and have to go pick it up anyway. At least the fed ex guy will get out of his truck.

Just ordered more parts.  Again.  How is it my local jobbers can't touch Rock Auto pricing?

In reply to SkinnyG :

No idea. I've actually bought a few parts locally just due to RA price plus shipping is within a few dollars of locals, and I don't have to wait. But you better believe I cross shop the hell out of them. For some things RA can't be touched though. Like the hubs I just bought for the wifes daily. 2 loaded hubs, shipped ups ground were cheaper than 1 unloaded hub locally.

I appreciate these codes. Bought some shocks and a water pump a few weeks back.
