Hmm, I buy quite a bit of stuff from the states and it really depends.
If being sent through normal postal sources then you have VAT at 17.5% plus normally a Royal Mail handling charge which seems to be anything they like, I would allow at least 30% for all fees combined but it may come in anywhere between 20-30%.
If its sent by a courier then you may only have to pay 17.5% but you need to check with the courier first.
As to post and packing if you scroll down their advert(!) it is $119.99 which roughly is £60 but it varies by the minute.
