限时抢购
限时抢购可提供在短时间内出售大量产品的好机会，但如果您预计结账量会大幅增加，则需要进行一些准备。在大多数情况下，只有在您开展限时抢购活动，并预计在几分钟的时间内有成百上千的客户结账时，我们才建议进行这些特殊的准备。
例如，Shadi 通常每天有 10,000 名访客和 100 个订单。他正在开展限时抢购活动，预计在 24 小时内有 50,000 名访客和 1000 个订单。此次促销不需要任何特殊准备。后来，Shadi 的商店在一家主流网络媒体中被列为推荐商店，并且他们设置了限时抢购活动以利用此次推荐。他们预计需求量会大幅增长，数以万计的客户将会参与抢购，每次补货后，库存会在几分钟内售完。这是幅度非常大的增长，因此需要进行一些准备以确保限时抢购顺利进行。
提前计划
如果您确定限时抢购产生的订单量能够达到您需要提前准备的水平，那么您应该尽快开始准备。适当的情况下，请提前几周进行准备以确保您有足够的时间。
准备预览产品
如果您想提供要在限时抢购期间提供的产品的预览，请创建独特的预览产品，使其不同于您要在活动开始时实际供应销售的产品。向在线商店发布有库存的产品时，客户可以完成这些产品的结账流程。尽管某些模板修改可隐藏添加到购物车操作，但这不会阻碍客户购买产品。
查看产品信息以便进行国际销售
如果您进行跨国销售并收取关税和进口税，请考虑不要在促销完成之前收取关税和进口税。如果您决定在促销期间收取关税和进口税，请查看您的促销产品，确认它们具有以下信息：
HS 编码
原产地
产品类别
确保您对销售产品填写这些字段有助于估算关税和进口税成本。如果您的产品没有 HS 编码或产品类型，则将不会针对该产品计算关税和进口税。
创建品牌化的密码页面
如果第三方的技术问题影响了您为客户提供服务的能力，最好的做法是锁定店面以防止问题恶化。如果您激活了密码页面，新访客将无法在您商店中创建新的结账，但已进入结账流程的客户可以完成购买。锁定店面让您能够在后台执行更改和解决问题，同时让用户了解到您正在解决问题和恢复销售。
使用特定于活动的产品系列和产品页面创建模板
专门为您的促销产品创建产品系列，如果可能，请使用可突出显示和简化您的产品页面的模板。在促销期间展示精简的产品系列和产品页面，可为您的客户提供更轻松、更快速的结账体验。尤其应考虑禁用以下内容：
产品系列筛选菜单
推荐的产品
社交网络源
幻灯片或轮播视图
弹出窗口或增销功能
检查发货地点
验证您的商店中是否启用了多个地点。如果启用了多个地点，您应该考虑禁用发货地点，因为一些发货地点不会在促销期间为在线订单发货。促销结束后，您可以重新启用这些地点。
手动入账付款
如果您自动获取款项，则应考虑在限时抢购期间将设置更改为手动获取款项。手动获取款项可以避免在超额销售或取消订单的情况下可能产生的高额信用卡费用，并使您能够在付款完成和发货流程开始之前检查和验证订单是否合法。

Flash sales
Flash sales can provide great opportunities to sell a large quantity of products in a short period of time, but they can require some preparation if you're expecting a large increase in your checkouts. In most cases, special preparations are recommended only if you're running a flash sale and you expect tens of thousands of customers to start a checkout within a few minutes.
For example, Shadi usually gets 10,000 visitors and 100 orders per day. They're running a flash sale and expect 50,000 visitors and 1000 orders over a period of 24 hours. This sale doesn't require any special preparation. Later, Shadi's business is featured on a major network, and they set up a flash sale to take advantage of the feature. They expect a significant increase in demand, with tens of thousands of customers competing for inventory, with stock selling out in minutes each time it's restocked. That's a substantial increase, and requires some preparation to make sure the flash sale goes smoothly.
Plan in advance
If you determine that your flash sale will generate enough orders that you need to prepare in advance, then you should start as soon as possible. When appropriate, start your preparations weeks in advance to make sure you have time.
Prepare preview products
If you want to provide a preview of the products you're offering during your flash sale, then create unique preview products separate from the ones that you'll actually be offering for sale when the event begins. When you publish products to your online store with inventory available, customers are able to complete a checkout with those products. While some theme modifications can hide Add to cart actions, these shouldn't be relied on to stop customers from purchasing.
Review product information for international sales
If you sell internationally and collect duty and import taxes, then consider disabling the collection of duty and import taxes until your sale is complete. If you decide to collect duty and import taxes during your sale, then review your sale products to verify that they have the following information:
HS codes
Country or region of origin
Product type
Ensuring that you have these fields filled out on your sale products helps to estimate duties and import tax costs. If your product does not have an HS code or a product type, duties and import tax will not be calculated for that product.
Create a branded password page
In the event that a technical issue with a third party affects your ability to serve your customers, the best course of action is to lock your storefront to prevent the issue from getting any worse. If you activate your password page, then new visitors are unable to create a new checkout in your store, but customers already in the process of checking out can complete their purchases. Locking your storefront lets you to make changes and resolve the issue in the background, and assure users that you're working to resolve the issue and resume your sale.
Create a theme with event-specific collections and product pages
Create a collection specifically for your sale items and, if possible, a theme that highlights and simplifies your product pages. Showing streamlined collections and product pages during the sale provides an easier, faster checkout experience for your customers. In particular, consider disabling the following:
Collection filtering menus
Recommended products
Social network feeds
Slideshow or carousel views
Popups or upsell functions
Check fulfillment locations
Verify whether multiple locations are enabled in your store. If they are, then you should consider disabling fulfillment locations that aren't fulfilling online orders for the duration of the sale. You can re-enable them after your sale is complete.
Capture payments manually
If you capture payments automatically, then you should consider changing your settings to capture payments manually for the duration of your flash sale. Capturing payments manually avoids potentially high credit card fees in the event of overselling or cancelled orders, and allows you to review and verify that orders are legitimate before the payment is completed and the fulfillment process starts.
