Probably £100 - £150 a month for a basic server. Probably needs to be PCI compliant for the cards so a fair bit more.
You would then probably need a decent firewall so that you can setup a site to site VPN with all of the in store systems so that the in store thing talks to it.

Companies as big as CCFC should really colocate their own equipment in a proper datacentre with 10gig internet connections etc.
It's not even that big a company now, an average sized supermarket turnover is around £50m compared to our turnover of c£10.5 in the championship, £5-6.5m league one.
