Bingbanners is a good company
I sent a jpg file to make a 3x4 poster. The next day I got an email advising me the low resolution. After improvement the file was used and a poster was delivered two days later by regular UPS. I am very happy with the work.when I did the third poster, the shipment was bent resulted in a crumpled up poster. I sent the proof by photos. I got a replacement shipped in a stronger shipping tube. Great job! A good company!
