I have been ordering from DVOR for a couple of years without many issues other than long ship times. This last order was shipped and when I went to their website to check status, I noticed the item was $21 cheaper. I did a online chat with C/S and they told me that they couldn't refund me the money because of an agreement with the manufacture on sale items. I would have to receive the item, return the item for credit then order the item again with the new price. I told them they would lose money on the deal doing it that way but they said that was the only to do it. I was not worth the hassle. I told him to cancel my order along with my back ordered item and to also remove my name from their mailing list and he couldn't type back fast enough saying OK. Great customer service.
EDIT: Spoke to C/S supervisor and told him the problem and he couldn't understand why the online c/s rep wouldn't accommodate my request. He gladly refunded me the difference and said he would speak with the c/s rep.
