Free google play IAP plugins?

Does anyone here know a good free IAP plugin for android? I’m trying to use sdkbox’s one but there’s no response from the application even though everything is well set-up…

Thank you!

Hi guys,

I have the same question. Is there any free IAP plugin for Unity 4.6.x?
I’ve also tried to use SDKBOX in my game. After many trials and errors I wasn’t able to set it up to initialize without errors.
Although, I think I’ve got pretty far, because It somehow gets current list of products and prices from the service, but on attempt to buy it says that specified product is not available. Now I’m stuck, since creators don’t answer their email.

If anyone is intersted in helping me solve rest errors I’m dealing with, just let me know, we can discuss that in another thread.
