Expensive products are the only way with CPS?
There are actually very few niche who can pull this like gym equipment or rolex watches maybe some collectible items too? these aren't niche that im profficient with. Most succesfull affiliate shops i found don't sell expensive products, so i wonder is it really more ev to go after very expensive products? especially if you have no idea about the niche? the only niche i know is card games, i was thinking to build an affiliate mtg store but im not sure if that would work well.
Shall i give up on expensive products and mix ppc with cps?
