How can I force combining of products? (Mobile phone store)

Hi all,

If this is posted in the wrong place or has been answered before then i do apologise.

I am modifying a mobile phone website for a friend - https://www.apltelecom.co.uk

For the Pay as you go mobile phones he would like it like carphone warehouse have theirs eg:

Nokia 6300 costs £69.95 when bought with £10 airtime (total paid = £79.95)

How do i modify the site to include:

"When bought with £10 airtime"

underneath the price, and then also for the cart to actually add the £10 onto the total???

Hope that makes sense

Cheers

Craig

You could use attributes - the basic phone, then the attribute would be 'with $10 airtime +$10'. That way you could offer other airtime amounts just by adding attributes.
