Finally my PI arrived, order number was 62xxx.

I can't believe, a couple of minutes after my post from 6:00 I got the DHL shipment notification email.
Looks like R.S. is just a couple of 1.000's behind their plan.
Will post again upon arrival.

Same here, order confirmed on 31.05.
Order number 62xxx , despatch time 6 weeks, haven't heard anything from R.S.
Still waiting ...
