Isle of Wight Ferry Deals

I've found two Isle of Wight Ferry deals that look like they save you up to £100 on a return ferry crossing. They're supposed to only be used in conjunction with a Break Free / Daily Mail Travel holiday, but the codes and links to the booking forms work without any restriction so it seems to be open to all. All it says is you need to print out the voucher (it's just a PDF) and take it with you to the ferry check-in.

I'm going to use this to save some money on our summer holiday. I wondered if anyone else had come across these deals as I've not seen them mentioned in any forums or voucher sites before.

These are the links. Sorry, i'm new to this forum. it doesn't seem to allow posting links, but you need to visit the pages below to get the offers.

I've only just signed up for this forum so it won't let me post the links. Can anyone help me? :j

The Red Funnel one looks like the biggest cost saving with returns as cheap as £54.50.

It looks like the offer is only open until the end of February.
