What no envelopes??

Everything arrived on time for the March Monthly edition, it all fell neatly into place and the printers chuntered away thundering out several thousand sheets. BUT and this is a big but it's now 4.30pm and we've not had this weeks delivery of paper and envelopes, we're already one delivery adrift so we've used our surplus envelopes and at the moment we're 400 – 500 envelopes short. We realised this may be problem yesterday and ordered more envelopes from another supplier who promised delivery today – but they're not here yet either (but the free gift is!). To get the Monthly out for Royal Mail they all have to ready to go by 7am tomorrow morning at the latest. I have a horrible feeling we may end up folding by hand 500 copies of CJS Monthly – RSI here we come.
