Intro specials

And don’t forget to check out the big introductory special discounts that we offer to celebrate our new product releases. These are limited to the first 100 customers who use each intro special coupon code, and many still have uses left. Here are the three most recent ones:

And more…

Visit our Specials page for a full list of all the remaining intro special deals and other specially discounted items. Note: You will need to add the intro special coupon codes to your cart manually; these are not automatically added when you click the “add all coupons to cart” link.

Disclaimers: These coupons can be combined to save on multiple products in a single order, but multiple coupons that apply to the same product cannot be combined; the one that gives the larger discount will automatically be applied. When multiple coupons can apply to the same item, the various discounts could appear on the line item description even if only one coupon applies. For instance, a $10.00 item with a coupon making it $9.00 and a 15% off coupon could show both the $1.00 discount and the $1.50 discount, but the final price will be $8.50 since only the bigger discount will apply.

Some coupons impose quantity restrictions that are intended to be “per customer”; if a customer places multiple orders in an attempt to get around coupon quantity restrictions, we will cancel all but the initial order. It is acceptable to use the same coupon in multiple orders in a way that does not violate its per-customer quantity restrictions.

The percentage-off coupons are discounts relative to the applicable retail price break (before any relevant price-break upgrade coupons are applied). The coupons can be applied to backorders if a sale item runs out of stock and is backorderable; if an item is not backorderable, discounts will be limited to available stock.
