Shipment for Virtual Products - does it work with 3rd party themes?

[freeme]

Hi,
I need a plugin for selling coupons - I found "Shipment for Virtual Products" (http://virtuemart.cloudaccess.net/extensions-virtuemart-2/shipment-for-virtual-products-detail). It looks like it fullfills all my needs and its from the core development team, which I also like.

On my VM 2.0.2 shop, I am using the theme Lightroom from YAGENDOO (http://www.yagendoo.com/en/joomla/extension-themes/virtuemart-themes/yag-lightroom-vmt.html)

So my question would be: is the Shipment for Virtual Products plugin compatible with 3rd party themes in general? Can I use both together? Would be good to know, before I spend the 35€.

Thx.
