Fidelity has two 50pt contracts for a September UY at $90 per point. If you go with the September UY you would just transfer the 50 points into your Oct contract and treat the whole thing as a September UY
i.e. you bank as if it was a Sept UY. I would move quickly if you are interested, that is a great deal and there are two to choose from...the $95 per point has 2013 points, not sure why they $90 one does not....
Second comment, fidelity can be difficult to deal with but as long as you stay on top of the timeline and stay involved you will do fine and save more then 2 grand... Buying direct is fine if it is your first purchase or you absolutely want the same UY but having just two is manageable. More then two...
