I ordered my rack three weeks before I needed a DA Photo, I had to mail a state ribbon to the company to add to my rack. I called them a week later and they had not received it yet, I talked to a representative his name started with Z and ended with K (four letters) he said he would check and call me the next day, he never did, he also did not annotate my file. I did talk to someone else, but bottom line it took over three weeks to get my ribbon rack.
If you do buy from USAMM you will not be disappointed again the rack looks amazing way better than I can do myself. Just make sure you have ample time before you need it.
