@Monk3e Matt you have a point that free stuff provides a company with necessary advertisiment and attracts people. My point is that it looks like people are just too inclined towards free stuff, when power user page went away people were upset because they could not get free stuff anymore.
Not saying to completely stop giveaways, just suggesting to reduce the frequency. Alternatively anker can run more of buy one get one kind of promotions where people are encouraged to buy as well (a lot of companies run such promotions including mountain dew )
