About Kit products

As in the feature list ,Nop Commerce 1.4 supports kit products (e.g. Build your own computer).

Can anybody give me the outline of how to buy a kit product. For e.g., I want my cusotmer to purchase phone and plan  (e.g., $99.99 unlimited plan) as a kit.I created phone and plan as two different product. Here I should not allow my customer to purchase 2 phones and 1 plan, which is logically wrong(perhaps 2 phones and 2 plans are quite acceptable). Please suggest me on this scenario.

Thanks
Venkat

hmmmm haven't tried this feature in 1.4 yet.

You can create kit products using product variants. Here is an example

Is there any way in a future edition to auto-update the price as you pick attributes in a kit like this (on same page as you select them? I've got customized code that does it based on 1.2 code; but obviously that does not help everyday users of 1.4
