If you order from RS then they usually have the stock by Friday. This is if they actually have the stock at their cntral warehouse? You should ask when they expect new stock and don't expect them to call back if they get any units in. Many people have previously posted about RS failing to contact them when the items they've reserved have been delivered to the stores. If they give you a date they'll have it in stock then ring them back yourself on that day.I have yes, out of stock at the moment. They can order in but usually takes a bit of time. May end up using them if I can't find any shop with them in stock.
