Since Bid and Price Drop are still broadcasting and appearing on the EPG, I can only assume they have paid for their bandwidth and other associated costs in advance. As it is KMPG's job to maximise the value of the Bid Shopping assets, it surprises me that they have't used the airtime for something. Why aren't they selling the already paid for airtime to Accurate Teleshopping or JML or someone?
According to Sky policy:
Sky
EPG fees are, it would appear, paid for monthly in advance. These appear not to be refunded if you transfer an EPG place to somebody else partway through the month.
28 days notice is ideally needed to Sky to reuse an EPG vacated by another broadcaster.
Under that arrangement, it's probably not worth selling it to somebody else, as by the time notice has been given and granted, you're only going to get two or three days out of it anyway.
I dare say, depending on when the invoice was last paid to Sky, channels 645 and 654 will be gone by the middle of May, or possibly towards the back end of the month.
