I spoke with Photographers Supply in San Francisco a while back and they have pretty much stopped ordering from Light Impressions. Photographers Supply said that their orders had way too many back ordered item and that for example on a recent order they had received 3 out of 30 items ordered. This conservation came about because I was inquiring about a LI item that was out of stock.
I was also angry when LI start hammering me with marketing emails. Quite doubtful that I'll ever order from them again.
