Points to be aware of with Appikon ‑ Pre‑Order (formerly Pre‑order Today)
The admin screen and help page are not available in Japanese

The admin screen, help page, and customer support for Appikon ‑ Pre‑Order are not available in Japanese. If you're not comfortable with English, there may be hidden work costs involved when you need to make detailed configuration changes or respond to issues.
Inventory conditions cannot be configured
Pre-order sales with Appikon ‑ Pre‑Order can only be used when a product is out of stock. If you want to always offer pre-order sales, you would need to set the product's inventory count to 0. This kind of operation is prone to mistakes, and the inability to configure pre-order conditions can make inventory management more cumbersome.
Pre-order sales are not available outside of product pages

Appikon ‑ Pre‑Order only supports pre-order sales on product pages. Note that pre-order sales are not possible on pages that use a collection page or featured product (or featured collection) section block for selling. To prevent unintended orders, you need to hide the cart button on pages other than product pages.
No bundling control
Since pre-order products and regular products ship at different times, there are cases where you don't want them purchased together. Appikon ‑ Pre‑Order has no bundling control feature, so you cannot prevent a pre-order product and a regular product from being ordered together.
No translation support
The text data in Appikon ‑ Pre‑Order supports only one language and cannot be translated. So if you're running a cross-border store on Shopify, this is something to be aware of.
