How long does it take for CeX to deliver?

I'm curious to know, can you provide me with an estimate on how long it typically takes for CeX to deliver a purchased item? Do they have a standard shipping timeline, or does it vary depending on the product and location? Additionally, are there any expedited shipping options available for those who require their purchases sooner rather than later? It would be great if you could shed some light on the delivery process and timeline for CeX.
