When you order from PCS your order is put at the bottom of the pile, you slowly move up the pile as orders ahead of you are built. Sometimes you will get to the top of the pile and be missing a component, in that case i presume you go into a pile marked 'waiting for x component'. Sometimes while your waiting for the component to come back into stock you are caught out again by a 2nd component going out of stock and you need to wait for that. That seems quite rare but it's all down to the way PCS have decided to use their stock.
As far as i understand, when you place an order you don't reserve stock for your machine it just marks you down as wanting those components. If it comes time to build and any of those components are out of stock then your a little bit stuck. Why they do it that way, im not sure, i would guess that it allows them more efficient stock control. The last thing they want when your ordering for the first time from an internet company you have never heard of before is "sorry A,B,C,D and E items are out fo stock" people will just move on. If PCS can keep minimal stock of items and provide the majority of orders on time i see no problems, but possibly a bit more of a visable explantion might be helpful.
Ahh see this is what I was looking for. Like I mentioned before, I wasn't really complaining because I myself don't know the specifics of how they operate. As a general customer of any product though, ordering and getting your parts "reserved" is what I would assume would happen. After you explained this, I do understand and agree that it does help them maintain good stock levels without over-ordering anything and in turn losing profit if they find it hard to sell the components.
The downside is for people that do need it in a certain amount of time, it is near on impossible to have a 90% successful estimate of how long it would take if there are pre-sold components, up until you are very close to the building stage in the queue. That also causes a problem like, for me, I've always wanted to order the Fast Track if I could, but since I can't until all the components of my build are present and assured to me, I can't get the priority service which I need, and still makes me every bit as vulnerable as someone who ordered the standard delivery and has no intention of fast tracking whatsoever, to have a component go out of stock before I get to my "turn" in the building stage.
Apparently my build could start tomorrow, so that's good, and if tomorrow all the parts are indeed present, I can order the Fast Track to make sure I get it before I go abroad. The thing is, it's very painful to shell out at least £39 more for something I've already waited almost 2 weeks for to start building. I guess that's just down to each individual, and how important it is to get their orders ASAP. I'm unhappy with that, and am still undecided if I should go for the Fast Track, but to be honest there's nothing I could do about it, and again it's down to the individual to make that decision and I don't fault PCS for that.
Now it's not officially a complaint, it's more I saw the pros and cons of the system, obviously with the information that I have until the guys at PCS can give a clearer picture.
