How does billing work?

We’re a monthly subscription which means, when you sign-up (unless you’re pre-paying a specific gift amount), you will be billed each month on the same day as your initial order, in advance of your next shipment. Shipments go out once a month, usually around the 4th or the 6th. Need your renewal payment date changed? No problem! Send us an email with your request!

Orders will show on your account page as “Processing” until the shipment is complete, then you will receive an email that the order is “Shipped” each month when your Siren Swag Bag ships. When you are billed each month for the following month’s bag, you will receive an email letting you know your subscription has been renewed automatically for the month.

What is the month’s deadline to get the next box?

We generally ship around the 4th-6th of the month.

The cut off for each month is at 11:59pm on the last day of the prior month. Therefore, an order for a currently featured month can be placed from the 1st of one month through the last (28th, 29th, 30th, 31st depending on the month) of the following to receive the upcoming delivery. For example:

To receive October’s Siren Swag Bag, orders must be placed between September 1 – September 30th. October’s Siren Swag Bag will then be mailed between October 4th and 6th.

October 1st – October 31st = November’s Siren Swag Bag

November 1st – November 30th = December’s Siren Swag Bag

December 1st – December 31st = January’s Siren Swag Bag

If you’d like more clarification or to know if you’ve made this month’s deadline, feel free to email us at

How do you ship?

The Filthy Mermaid™ ships via USPS First Class Mail to all US states (including Alaska & Hawaii), territories, and APO addresses. APO addresses should allow up to 7 days additional delivery time. Canadian and other International addresses should allow an additional 7-10 days delivery time.

How do I add a gift message?

If you’re giving Siren Swag Bags as a gift, you may include a gift message at the order. Simply type your message into the “Add a message” note box (don’t forget to include who it’s for and who it’s from) below the size and quantity sections and we’ll be sure to include your handwritten note on one of our signature Filthy Mermaid™ cards.

How do I cancel?

While our hearts will sink to the depths of the sea should you choose to leave us, you are welcome to cancel your subscription at any time by logging into your account and cancelling your subscription. Should you have trouble cancelling yourself, you may request us to cancel on your behalf by emailing us at

Please note that cancellations received after the monthly renewal date each month will be committed to the coming month’s bag, but will not be charged for any bags following that shipment.

Please also note that due to the discounted, prepaid nature of our 3, 6, and 12 month gift subscription packages, they are non-refundable. Customers wishing to discontinue receiving the remainder of their shipments are welcome to transfer them to a fellow mermaid without fee.

How do I receive a refund?

If you would like to receive a refund, you must request it prior to the shipment of your package. Unfortunately, we are unable to provide refunds for Siren Swags Bags after your shipment has left us.
