The first order depends on the time of month you order. If you subscribe to a topper club before the cut-off time (usually the 17th), you will receive your first order before the end of the month.
For example, if the cut-off time is the 17th and you order on the 14th @ 11:59pm EST, you will receive your order before the end of the month.
Topper club orders placed after the cut-off time (e.g the 17th @ 12am EST), will ship out at any time the following month. E.G The order is placed on Feb 17th and is delivered during the month of March.
