OpenSky BEWARE!! They change the cost when you go to check out!! Internet

I found this company when looking for gifts for my girlfriend. I wend through roughly a couple hundred items, and when I liked one, I would open it ina new window, and add it to my cart. In total I had 7 items in my cart. When I went to check out I noticed the prices on 4 of the 7 items I added were all about $2.00-$6.00 more than what was listed. I immediately did an online chat with a representative who asked for the specific items. I also sent them screen shots of the advertised prices, as well as the screen shot of my cart (which were the same items, but just higher prices). They took about 5-6 minutes and then asked me to refresh the pages of the items I was looking at. When I did all of the prices then changed to the prices in my cart!! They literally went into the items and changed the prices and updated them to try to cover themselves. I asked for the items to be at the orignal prices so I can purchase them and they told me all they can do is give me a credit on my "next order". Well, there isn't going to be First order or a next order because of this!!
