Our Holiday Sale 10% off sitewide offer is already an incredible deal, providing you with the lowest prices of the year. While this deep discount cannot be combined with most other offers due to cost limitations, the good news is it can still be combined with our 5% local-pickup discount and the $50 cash back promotion for even greater savings!

No, the 10% discount has no purchase amount limit. You can get the discount on any product with code XMAS, but the quantity of products is limited. If you like it, please buy it as soon as possible.

Yes, you can! For example, if you buy a pair of AD80 ($795) with 10% Holiday Sale discount, and you pick them up at our warehouse in CA, and you refer a friend to buy, you will get them at the price of $625.75! What a deal!
