Groupon clone#

Hi, yesterday a customer called me to make an estimate for designing a Groupon clone

Does anyone have experience with this? Would this be possible with Visioncart in Revo?

I never used Groupon before, so I need to know what a website like Groupon contains and if it's possible to make in modx Revo.
There are some premade Groupon scripts, but I think I get stuck when the customer asks for custom modules.

thanks in advance

Yes it is possible. Either you build the cart yourself, or use foxycart or visioncart for example.
Obv you will need to develop the functionality of the site yourself if you want it to be good.
