Items in stock will appear on the product page, and both size/colour attributes will be selectable.
If the item is out of stock in the particular colour/size you want, two options will show:
"Notify Me" - in this section you can put your email address in, as soon as the product arrives and we update the stock levels, you will be notified within seconds of their arrival.
"Pre Order" - the drop down menu / button will read Pre Order if the item is not in stock, but available soon. Generally, pre order items are listed and available for dispatch within 4 weeks of their arrival. If we have a firm E.T.A, this date will be listed to keep you updated!
