They have contacted me I dont understand why they are hiding the prices maybe they are giving different prices for different people which is not honest.Their prices are not so good in my opinion: $0,25 each (or $0,15 for amounts above 10,000 installs).
We do our best to give high quality services at competitive prices. We are sure of the conveniente of our costs and we have never hided prices or cheated anyone.
Unfortunately your sentence is generic; Prices may vary accordingly to customers requests ($0,15-$0,50): geo-target campaign, retention, and many other features that could considerably increase or decrease the price per install. You neither included seasonal special offers or other discounts that may apply. We are sorry to read your disappointment on the convenience of our prices, hope you can find better ones at the same quality.
