First off, I'm sorry for seeming angry and such.... But you gotta understand.
No i don't want your full pack, that one plugin is not worth $25 and frankly i don't want/need the other ones.
On the other hand, If i do want the single plugin i have to download your app, download some more apps, post to facebook and get coins. I do understand that it is free if i do that which is nice of you.
Now if i may make a suggestion. Create a website, list the plugins there with a storefront, And have them broken down to something like $5 a plugin or whatever you think is fair. You could also list the full plugin pack for a deal to give more incentive to purchase the entire thing over $5 a plugin.
Obviously this is all just my opinion but if you had a real storefront with more options I would have been able to buy it and probably go back and buy another if i needed it.
