VR Online Shopping Frustration

The Victor and Rolf hysteria continues... At 00:01 parts of the designer collection were launched at H&M for online shopping. Still craving for the trench (that I was not allowed to buy from the store as the one I found in the store had a rift on it's arm and therefore had to be sent back to the the head office...), I logged on to the site in due time.
The speed was extremely slow, but at last I managed to click on the trench icon, get the right size in the shopping bag and proceed to check out. Everything seemed to work surprisingly fine. The jacked was almost mine!
But then, as the order was verified the trench suddenly turned out to be sold out! Really annoying when I had "reserved" it in my shopping bag.
Thus, I ended up with nothing but frustration and an hour less sleep...
Did anyone of you have similar experiences?
