No Problem Your Welcome . I confirmed that Shop Mod works with almost all mods and even the affiliate mod so it breaks nothing but i would suggest users to install the Shop mod as the first mod on their forums so its installed flawlessly.
You can see it working perfectly with following mods on my forums :
