From an email I received:

Aircooled.Net VW Parts Labor Day Week-Long SALE!
Get 10% off Online Orders through Sept 2nd, 2013!!
(on qualifying orders of $100.00 or more)
Enter the following Sale PROMOCODE: 0813USALD10 in your Autopart Cart prior to proceeding into the checkout area.


How the Promocode / Sale works:


** Promocodes are ONLY good for online orders placed at http://vwparts.aircooled.net (not valid on phone, email, or mail-in orders).


** You MUST select/allow fulfillment of any requested items that are backordered for the discount to remain valid. Code and discount will be removed / invalid if you select 'cancel backorders' as your backorder handling preference, or if you email to cancel backorders at any point in order processing.


**This offer cannot be combined with any other discount offers or promotions. Only one promotion code can be redeemed per order.


** Promocodes must be entered while the products are in your Autopart Cart BEFORE you enter checkout. A Promocode Discount CANNOT be applied retroactively after an order is submitted, or to pending or previously submitted orders/backorders.


** Promocode can be used for an unlimited number of qualifying online orders (minimum order to qualify is $100.00) between August 26 and Sept 2nd, 2013.


** Promocode discounts apply only to regular priced merchandise (including made-to-order, special order, and custom made items). Discounts do not apply to already sale-priced items, labor/modification fees, refundable core charges, or shipping costs. Your adjusted discount amount will be applied at time of payment processing and invoicing (which occurs on the date of shipment, NOT at the time of order submission). So your final discount amount may vary from the amount quoted at time of order submission, as it will be based on the final amount for items that ship to you.
