How much would you pay for the Premium addons?

As our addons are getting ready for the beta release, we want the price to be fair and comfortable for you. So, we would like to know how much you think the addons are worth paying for.
We would be charging a one-time fee (with LIFETIME LICENSE) for all addons with free updates for 1 year and all subsequent optional updates will be charged yearly in the order of 50% or lesser than the actual addon price.

Please follow the link below to fill in your price for the addons.
