I think this is best posted in technical as it's where people come looking for advice on parts and suppliers. Mods, feel free to move it if you think it should be elsewhere.
I use Rockauto as shipping cost to the UK is good. Prices seem reasonable to me to but I can't get a lot of parts easily over here without paying a premium. As I've just bought some bits recently I've been sent an email offering a 5% discount which it says to share so here it is. I don't know how prices will compare in the US but it's got to be worth a look...
Thank you for being a www.RockAuto.com customer! To show our appreciation, we have a special discount for you.
Your discount code is:
Here's how to use it:
* Enter your code in the "How did you hear about us" line of the shopping cart.
* If you are using our traditional HTML catalog, please click the "Set" button to the right of the field.
* Your discount will automatically appear, subtracted from your order total.
**NOTE: We sometimes get calls from people who put the word "discount" in front of their code and do not get the discount. Please enter ONLY the discount code, no other words or numbers.**
The discount takes 5% off our already-low prices, and there's no limit on order size or the number of orders. Use the code for your next order, and share the code with friends, neighbors, relatives, the guy at the corner garage--anyone you know who works on cars or trucks.
This discount code expires on April 15, 2008; so don't wait!
