A presale allows you to collect orders for items that are not yet in stock. Additionally, they inform the Amplifier service team and your customers (by way of the Amplifier order status tool) as to the terms of the oversale, and the expected restock date. It is also expected that your customers will be notified of the presale at some point during order placement. Orders placed for oversold items will be canceled by Amplifier unless a presale is date range is set in your my.amplifier.com/items section. It is also worth reviewing the Federal Trade Commission’s Business Guide to the FTC's Mail, Internet, or Telephone Order Merchandise Rule.
