In Spain, that model seems like the Unicorn, theoretically meant to be in "Stock" but no store has them, maybe they appear and they fly away so fast that I'm unable to see the availability, seems plausible.
I know it's a bummer to have to wait again, but I think it's the best option if you need the machine ASAP; if you place an order now, I think you'll have about 1.5-2 weeks to lurk around for any available stock before Apple charges you and starts the real process so you can cancel it, if not, then just 2 weeks more and the machine will be with you.
If you're curious/interested regarding local stock, there are some tools to check via the store code so you can lurk multiple ones w/o having to hassle with Apple's website directly.
Here you can find one of those, meant to be used with Node.js and checking just MBP14/MBP16 (UK is supported AFAIK)
