A presale is activated for an item by entering a presale date range for an item in your my.amplifier.com/items section. To edit the presale date range for an item, click on the SKU value to edit individually and update the presale date range attribute as desired. The attribute can also be updated via bulk change or the item export/import function. Amplifier will report availability via our API based on the date range set.
Note, this setting will not proactively notify customers of presale during checkout in your online store. You are still responsible for notifying your customers of presale, per the Federal Trade Commission’s Business Guide to the FTC's Mail, Internet, or Telephone Order Merchandise Rule.
