I think so but one domain for £1.48 is not that bad.
Used Namecheap yesterday for a Comodo SSL - seemed to be the cheapest for a 3 domain cert
its a good and cheap way to encrypt your website but your hosting provider should support it (pirate)
But this is still a basic cert, so why not just save all your money and the hassle, and go with Letsencrypt?
Oh I'm so sorry. But you can contact namecheap customer service and ask this offer. Today I did the same. Actually I got 2 $0.88 coupons from black friday offer. But unfortunately it expired. They didn't give me $0.88 offer but this ;)
