Eaglemoss puts out 1:21 scale die-cast lead figurines from a variety of genre/media franchises (I've posted about my Eaglemoss Captain Britain figure here before), and allows buyers to purchase subscriptions to their lines. Each figure also comes with a biographical magazine featuring the character of the month. On their own, the figures usually retail for between $15 and $25 USD.
Personally, my interests are too narrow for a subscription, so I've always waited for the reviews to come in and then picked up the ones I wanted on the secondary market. Since I've never wanted to pay a premium for any of them, that often means waiting forever until a deal comes along - but this time I lucked out and found this one at a reasonable price on eBay the first time I looked!
