No, Duet Inc. typically allows only one promo code per order. Their checkout system is designed to accept a single promotional discount at checkout, and attempting to enter multiple codes will usually result in only the most recently entered code being applied.

If you have multiple promo codes, you should:

1. Compare the discount amounts to determine which offers the best value.
2. Consider the specific items in your cart and which code applies to more of your purchases.
3. Choose the code that provides the highest overall discount for your particular order.

Some Duet Inc. promotions may automatically combine with ongoing sales or clearance discounts, but these are system-applied rather than requiring additional promo codes.

Pro tip: If you're unsure which of your promo codes will provide the best savings, you can test each one by entering it at checkout and noting the discount before finalizing your purchase. Just remember to remove any previously applied code before testing a new one.

Most Duet Inc. promo codes can be applied to regular-priced items, but their policy on sale items varies depending on the specific promotion. Here's what you should know:

• Standard promo codes typically exclude items already marked down or in the clearance section.
• Seasonal promotions sometimes allow code stacking on sale items during special events.
• Codes with language like "sitewide" or "everything" are more likely to work on sale merchandise.
• Percentage-off codes usually have more restrictions than dollar-amount discounts.
• Membership or loyalty discounts may have different rules regarding sale items.

The terms and conditions of each specific promo code will indicate whether sale items are excluded. This information is usually provided in the fine print associated with the promotion.

Pro tip: If you're specifically looking to save on sale items, watch for Duet Inc.'s special promotions advertised as "extra % off sale" or "sale on sale" events, which are specifically designed to provide additional discounts on already reduced merchandise.
