Dumb question regarding Bulldog Broadband pricing..

[GuruJockStrap]

Thinking of switching to Bulldog for broadband but I'm a bit confused with how it works.

Your order for XXXXXX

Broadband: Up to 8 meg Unlimited £19.50/mth

Phone: Bulldog Line £10.50/mth

Extras: Unlimited UK landline calls to numbers starting 01/02 £0.00/mth

-----------------------------------------------------
Total monthly cost: £30.00/mth

One-off items: No equipment required £0.00
Connection £99.00
-----------------------------------------------------
Total one-off cost £99.00

Your standard monthly cost after all offers have ended will be £42.00. This excludes the cost for the optional Internet Security Suite.

It might be because I'm tired but the last sentence has got me all confused. I thought the monthly cost is £30?

UBER QUICK EDIT: Whoops! Appears the Unlimited UK landline calls is an additional package free for the first 2 months and then £12 thereafter
