It's true, and you will have to weigh up the cost versus the benefits like I had to. For me, I tend to cycle through my games (if they don't get played, then I sell/pass them on) so I tend to reuse sleeves, which brings the cost down (it also keeps cards safe for resell value). In saying that, it's not the only good option. You could buy cheap Ultra Pro sleeves and just replace them more regularly if any wear out. Mayday Sleeves are also very good and durable (use them for non-standard card sizes). IMO Dragon Shield is just the best option 🙂
