How do cex pay?

Looking to sell an ipad and cex seem to have the best price. Can't find anywhere online as to how they pay and can't get through to them on the phone.
If I remember correctly from a few years back, they paid the money into my bank account, but it took a few days. Is this still the case? Going to buy a new ipad tomorrow so the cash would come in handy straight away.

Many thanks.

Edit: Taking it into store.
