I believe it is chronological order, whether courier method and payment method can slightly throw a spanner in works I do not know.
As with previous launches on a hot in demand product I'd always advice paying with a debit/credit card on OcUK's checkout and selecting DPD next day, this method should be the quickest method of checking out and is the majority of what our customers use, so that may help.
However we are on a new ERP nowadays and I have no clue how it works and no ability to interact with it, whereas I knew the old systems inside out because I had worked pretty much every role in OcUK from 2001 from sales, technical sales, technical, warehouse goodsin and packing, purchasing, marketing and website content. Now we are on a new ERP I am strictly purchasing so have less visibility which is a shame but the company is no longer operating out of a small unit with around 20 staff, its now a global operation. Saying that still for our size I think OcUK has maintained the personal touch very well which is incredibly hard to keep as companies grow.
Still I ask people be patient, as I say more stock is en-route and due within the next 7 days is a further 300-400 units which should guarantee every order is shipped that was placed on launch day before 14:15 and plenty of the orders placed between 14:15-14:30 we may even clear all those.
As I say I placed orders for 10,000 units back in October, so I judged the demand for this product very well, as such getting my orders in so early and also going big with the ordering should in theory guarantee OcUK very good allocation of waves 2 and 3 of incoming UK stocks.
Just need to be patient, as the saying goes all good things come to those who wait.
