Hi @Seller_JFFOkVft1GE7T.

Thank you for reaching out to the Amazon Seller Forums. I understand you're asking about the new strikethrough price policy released on March 31st, specifically regarding whether coupons count toward discount days and if combining coupons with price discounts might cause you to lose your strikethrough price after 45 days.

Based on Amazon's strikethrough pricing policies, here's what you need to know:

• Reference Price Requirements: The updated policy (effective March 31, 2023) changed the reference price logic from requiring "the price must be live for 28 out of trailing 90 days" to using the "median price over the last 35 days (T-35)." With this new logic, the price needs to be live for at least 1 day in the last 35 days and will not include any promotional price.
• Discount Thresholds: For a strikethrough price to display, your promotion must meet minimum discount criteria: the discount must be at least 5% AND at least $0.10 (for US marketplace) when compared to the valid reference price.

Coupons and Discount Days

Important: Coupons are treated differently from item-level price discounts in Amazon's system. The strikethrough price policy primarily tracks item-level promotions and does not include point-of-sale (POS) promotions like coupons in the same way.

Stacking Promotions: When you run coupons and price discounts simultaneously, these discounts will combine for the customer. For example, if a Lightning Deal offers a 20% discount on a $100 product and that same product also has a 5% off coupon running at the same time, these discounts will be combined, resulting in a total discount of $25.

Maintaining Your Strikethrough Price

To ensure you maintain a valid strikethrough price:

• Price Stability: Amazon has implemented price stabilization measures where prices are stabilized T-4 weeks before promotions go live to ensure a valid reference price exists.
• Avoid Extended Promotions: If an ASIN has had a promotion live for more than 5 weeks, it may not qualify for a reference price in the T-35 day lookback period.
• Monitor Your Promotional Calendar: Plan your promotions strategically to ensure you maintain sufficient non-promotional pricing history.

While coupons and price discounts can be set simultaneously, I recommend:

1. Monitoring the duration of your combined promotions
2. Ensuring you maintain regular pricing periods between promotional activities
3. Using Amazon's deals dashboard to track your promotional calendar

感谢您在亚马逊卖家论坛发帖咨询。我了解到您想问关于3月31日发布的新划线价政策，特别是优惠券是否计入折扣天数，以及同时使用优惠券和价格折扣是否会导致45天后失去划线价资格的问题。

根据亚马逊的划线价政策，以下是您需要了解的内容：

参考价格要求： 更新后的政策(2023年3月31日生效)将参考价格逻辑从"价格必须在过去90天内至少存在28天"改为使用"过去35天的中位价格(T-35)"。按照这个新逻辑，价格需要在过去35天内至少存在1天，并且不包括任何促销价格。

折扣门槛： 要显示划线价，您的促销必须满足最低折扣标准：与有效参考价格相比，折扣必须至少达到5%且至少$0.10(美国站点)。

优惠券与折扣天数 这里有个重要的区别：在亚马逊系统中，优惠券与商品级别的价格折扣是分开处理的。划线价政策主要追踪商品级别的促销，对于优惠券这类销售点(POS)促销的处理方式是不同的。

叠加促销： 当您同时运行优惠券和价格折扣时，这些折扣会为买家叠加。举个例子，如果一个秒杀活动对$100的商品提供20%折扣，同时该商品还有5%的优惠券在运行，这些折扣会叠加，最终总折扣为$25。

保持您的划线价资格 为了确保您保持有效的划线价，需要注意以下几点：

价格稳定性： 亚马逊实施了价格稳定措施，在促销开始前4周(T-4周)会稳定价格，以确保存在有效的参考价格。

避免长期促销： 如果某个ASIN的促销已经持续超过5周，它可能无法在T-35天回溯期内获得参考价格资格。

监控您的促销日历： 策略性地规划您的促销活动，确保保持足够的非促销定价历史记录。

建议 虽然优惠券和价格折扣可以同时设置，但我建议您：

密切关注叠加促销的持续时间，确保在促销活动之间保持常规定价周期，并利用亚马逊的促销仪表板来追踪您的促销日历安排。
