SitePoint

I purchased a digital download file from the learnable site a while back, using a link that looked to me like I was making a one-time-only fee for the information I downloaded. Hidden in their proposal text was language I did not see, that said I would also be receiving a "trial subscription" of some sort. That spurious and unwanted subscription, it turns out, would be free for a month. If I did not log back in and discontinue it I would then be charged $15 USA dollars a month. All subsequent emails from learnable went into my Spam folder. So a half a year later I noticed my credit card had been billed for a lot of money. Learnable refused to refund my money. I complained bitterly and finally got a pompous product support person to refund half the amount. Be careful. They'll relieve you from as much of your money as they can. Any way they can, apparently.

If you're looking to buy Sitepoint books, I think this is the best deal (except for some of their Christmas deals). For a $17/month membership, you can read all the books online, or use the credits (you get 2 per month) to download them.
