vBC can be used to control the points/cash in the shop, and it also has the vBookie integration provided... I just can't remember whether the link with vBookie is provided in the Lite version or not.
No worries. Fillip H. and Darkwaltz4 can be sure of the possibilities, but I already use the Pro versions of both to link between the two (and vBCredits can link with vBActivity as well). vBCredits is the best system for creating a 'master' currency which works with all of the mods at DBTech that require it, and has the scope to work with other mods outside of DBTech if they integrate it.
