Thanks, Superman! I thought
my aeria points total was strangely high this morning, and looking up the AP Purchase History page, there was "Matomy Contest Payout 2nd Place", 3,000 ap! Since I'm in Britain I have no idea how or if that "50 $ Coupons" thing will work, only time will tell, but the ap is the main thing, and very welcome.
I see I managed to watch around 62 Matomy videos over the two weeks, at their usual 1ap each... I did do one "task" as well, for 96 ap, which involved judging how good a match certain products were for shopping search terms - a weird mix, in the various sections, of autographed sports trading cards, computer accessories, real estate, fashion items, and more, it took quite a while to do.
So, these earn-free-ap offers work for me, though I generally only do the video ones, which of course vary from country to country.
