A digital product is something you use online or download: a design app, an office suite, a VPN. A service is the ongoing plan behind it. The price is often per month, per year, or per person.
When you compare them here, match the billing period before you match the price. A yearly plan shown as a monthly equivalent will look cheaper than a month-to-month plan. The note on a deal is there to say which one you are looking at.
Then check seats. A personal plan and a family or team plan are different products even when the brand name is the same. Storage, devices, and commercial use are the specs that usually decide it.
Cancellation sits with the provider. Compare Deals UK does not bill you and cannot refund a subscription. Open the offer, read who you pay, and keep that confirmation.
