Shop Policies

Thanks for shopping with Simpson_Math! Here are just a few details about our little math nerd and gamer pin shop.

Refunds and Returns

All sales are final. If you have any issues with your products please contact us.

Newsletter and Contact Information

The goal of our shop's email newsletter is to let our previous customers know when a new pin comes out. We promise not to spam your email account, we know how annoying that can be. Your email and contact information will be kept secure and not sold or given to any third party. You can sign up using the above link or at checkout.


Your privacy matters to us. Our shop has SSL, which adds a layer of security when you enter your information at checkout. Payments are processed by Stripe or Paypal, which have the highest level of security on all transactions.

If you are in Texas, y'all will notice an 8.25% sales tax charge at checkout. That's because we're in the same state. Howdy neighbor!

Our shop uses TaxJar, so states other than Texas and international orders might see a sales tax, based on their calculations. Our shop does not collect VAT for international orders.

Apple Pay and Google Pay are available on our shop. The nature of these payment methods only allows for purchase of a single item and without any coupon code applied. If you wish to order different products or use a coupon code, checkout using the cart.

When preordering an item in our shop, your card will be charged at the time of sale. Your item(s) will be shipped once we get them from our manufacturer. If you would like to cancel your preorder, contact us for a full refund. Usually, we will only ship once per order, so if an in-stock item is ordered with a preorder, we will ship them together once the preorder item(s) arrive.

"Standard" vs "B-Grade"?

Each pin is handmade, so minor imperfections are expected. We check all our pins for defects and those that meet our standards we sell as Standard-Grade.

B-Grade pins are those that we deem to have a minor defect. Often it is a defect that the average customer won't notice, but we the designers do. Pins with serious flaws are generally not sold at all.

Examples of a B-Grade:
  • Visible polishing lines
  • Slight metal discoloration
  • Scratches
  • Dust specks
