Was looking for a local print shop for my friend and Iās businesses and postnet did not disappoint! We needed business cards, foam board signage, and cardstock prints in a short period time and they got it done much faster than anticipated! Lily and Victor were very friendly and helpful and listened to the extra resizing i needed help with. The quality of the prints came out great with vivid colors. I will definitely be back in the future!

Eli helped me package my scornful piece and my limited edition pack of 1st edition pokemon cards. Although I would recommend a cool dark souls poster complement the interior color. Eli's shirt was easily the highlight of the visit, it was cool.
