Frequently Asked Questions


What are the Bestsellers and Standard Collections?
You may have noticed that Necessary & Sufficient Tees has a Standard Collection and Bestsellers Collection. The Standard Collection carries the majority of our awesome, geeky t-shirts, and you'll find the most variety of designs here. Our Bestsellers collection is home to our most popular shirts and special collaborative designs. The designs in our Bestseller Collection are all professionally screen printed for the highest quality shirt possible, and because of their popularity, we have reduced the prices on all shirts in this collection.

Why are there separate shopping carts for the Bestsellers and Standard Collections?
The shirts in our Bestseller collection are screen printed and fullfilled by professional screen printer, PrintMojo, while our Standard Collection is digitally printed by Cafepress. Because each company has their own inventory management system, we have a separate shopping cart for each collection.

Is it possible to combine orders from the Bestseller and Standard Collections?
Unfortunately, because two different printing companies fulfill and ship the shirts from our two collections, we're unable to combine orders at this time.

What's the difference between screen printing and digital printing?
Digital printing is a newer technology in t-shirt printing that has become very popular over the last few years and has seen a tremendous improvement in quality. Digital printing allows for the printing of complex or intricate designs with many colors. Screen printing is the traditional t-shirt printing process where screens are used as stencils to imprint ink directly on the shirt. Screen printing produces very high quality shirts, but the designs are often limited to fewer colors and simpler shapes because of the manual work needed to create the screens. Both techniques have their own benefits, and we take advantage of this by producing our different designs with the printing technique that fits them best.
