I ordered a 1x10 custom banner from my own PDF artwork. When I asked a pre-sales question, the sales staff got back with me in just a few minutes to let me know my file looked good to print and met their specs.
Because I ordered near Labor Day and my event was the following week they even let me call in and make a change to the shipping option last minute. It arrive just in time and looks great.
I was much happier with the price from signs in a snap compared to the local sign shop we have used in the past.
