Best current Amazon, comission junction, clickbank wordpress store builder?

HI, Can anyone tell me what is the best store builder for the mentioned affiliates in the title overall?

Some of the features I am looking for

- Noob friendly
- Cost upto $50 slightly more for developer license
- Can add content automatically and manually such as product descriptions etc
- Social media plugins
- works with autoresponders for building lists

I have looked at CovertStorebuilder. It looks nice but I read that its pricing is not accurate and some other issues.

thanks
