Frequently asked questions
What sizes do the t-shirts come in?
Unisex tees run S to 3XL with a relaxed cut. Fitted women s tees and racerback tanks run XS to 2XL. Each product page has a size chart with chest and length measurements.
What are the shirts made of and how is the design printed?
Pre shrunk combed cotton with a soft hand feel. Designs are direct to garment printed, so there is no plastic feel and the color holds through dozens of wash cycles. Wash inside out in cold water.
How long does shipping take from Geekpsters?
Every item is printed to order. Production takes 2 to 7 business days, then US delivery takes another 3 to 8 business days, so most US orders arrive within 5 to 13 business days. International orders take 10 to 30 business days after production. Shipping is free on US orders over $60 and you get a tracking number by email when it ships.
What is the return policy?
You have 60 days from delivery to request a return on unworn items with tags. Email contact@geekpsters.com with your order number to start. If the item is defective, damaged, or wrong, we replace it or refund you at no cost. For other returns the customer covers return shipping. Exchanges work as a return plus a new order.
Is Geekpsters print on demand?
Yes. Nothing is mass produced or sitting in a warehouse. Each shirt, hat, sticker, or bandana is printed when you order it, which is why production adds a few days and why there is no overstock waste.
Is this a good gift for a developer or tech person?
That is the whole point of the store. Geekpsters designs are written for programmers, DevOps and SRE engineers, AI and data people, gamers, and sci-fi fans, so the reference lands with the person who gets it. If you are unsure of a size, a hat, sticker, mug, or candle is a safe pick.
