If we don't have your desired item in stock then you can just contact us to see if we will have it back in stock again.
We can't always promise everything will be restocked and if you've found an item in a Sale category then it probably won't be restocked at all.
If you're desperate to find out about a specific item we can't promise we'll have the answer but you could try contacting us through our Contact Form and we may be able to help.
