Not every experience is bad...
I ordered 6 polyester and 2 vinyl backdrops. I paid extra for express shipping to get them before Christmas. My only issue was it took them a week to ship the package even though it said it was ready to ship 2 days after placing the order. I received everything that I ordered 4 days after it shipped, within the 3 - 5 day express window. All of my backdrops are beautiful and bright and I am so excited to use them. I set up a small shoot this past weekend with family to test them. I haven't processed the photos yet but so far am extremely happy with purchase.
