mental_floss store


Is your site secure?
The mental_floss store is hosted on SAS 70 Type II certified servers with hacker deterrent security provisioning, three redundant network architectures and hardware firewalls. We are also PCI compliant, and our entire network is independently audited against stringent PCI security standards every three months.

How do the shirts run size-wise?
Click here for a link to our sizing charts. Please note that when we say the women’s shirts are EXTREMELY small, we aren’t kidding.

Do your T-shirts shrink?
Most of our shirts are pre-shrunk 100% cotton. Even though they are pre-shrunk, shirts can still shrink. The extent of the shrinkage depends on the color and how you wash and dry the shirt. Click here for t-shirt sizing.

In the subscription /shirt special, can I send the shirt to one address and the subscription to another?
Sorry, the subscription / shirt special is a package deal and can’t be split apart.

Why did my credit card transaction fail?
If your are using a valid credit card and the transaction fails, there are a number of potential reasons. Please check the following: The CID code must be entered correctly – it’s the last three digits on the strip on the back of a MasterCard or Visa or the 4 digits to the top right of an American Express number. The billing address you enter must match where your credit card statement is sent. Your name must appear exactly as it does on your credit card, including your middle initial if it is on your credit card. If this still doesn’t work, contact us.

Why didn’t the discount code work?
If the discount did not calculate after you clicked ‘apply discount’, check to see that the discount date is still valid. Also, please note that promotions always exclude package deals, clearance and magazine subscriptions--unless otherwise noted. Coupon codes are not valid with previously ordered items, in combination with other coupon codes, or online gift certificates. Mental Floss, Inc. reserves the right to change or coupons at any time without notification.

I messed up my order, can I fix it?
If your order hasn’t already shipped, contact us and we will be happy to assist you.

How will I know if you got my order?
An invoice will appear on screen after you submit your payment. Print the invoice for your records but you’ll also receive a copy via email.

When will my order ship?
T-shirts ship directly from our printer and should be delivered in 7-10 business days. Most product orders ship within 3-4 business days via US Mail. If you ordered a subscription please allow 4-6 weeks for delivery of your first issue.

Do you offer package tracking?
Yes. If you'd like your tracking number, request it through our contact page. Please note, tracking information on t-shirts will not be available until the t-shirt has been printed, which may take 2-4 business days. Tracking information on items may not be available for 2-3 business days after your order. All of our packages are sent via US Mail with delivery confirmation tracking. US Mail packages can be tracked here. Be sure to provide a valid email address to receive the tracking number.

Do you ship to military addresses?
Yes! How could we not. Simply select APO or FPO from our drop-down lists.

Will I have to pay customs fees on my order?
Your international order may be subject to customs duties/fees when it arrives. Unfortunately, since mental_floss doesn't set or have control over these fees, we can't estimate what your charges will be. If you aren't familiar with the customs fees in your country, please check with your local customs office for more information. Because we are a retail store, we are not able to mark orders as 'Gifts' for customers to avoid paying these fees. In addition, we can't accommodate pre-payment of these fees for gift orders. The shipping charges you pay to mental_floss do NOT include customs fees, import taxes, brokerage fees, or duties. If you refuse to pay these customs fees when your order arrives, the shipment will be returned to mental_floss and we will be charged the customs fees plus return shipping costs. Therefore, we do not issue refunds for customs fees, shipping, or the cost of your order if you refuse to pay the customs fees as we incur additional costs. The delivery of your order may be delayed due to customs processing. If your order doesn't arrive in a reasonable amount of time, please check with your local customs office to see if they are holding your package for payment of fees. Some customs offices will send a separate invoice for your customs fees that might arrive several weeks after you receive your shipment. Please be familiar with the customs laws in your country before you order!
