I've never had any problems with ripping out Caron Simply Soft and reusing it, and I've done it a bunch (because I mess up a lot). I hope they haven't changed the quality of their yarns!
On the other hand, I've pretty much stopped buying any yarn from Hobby Lobby. They drastically downsized their yarn department several years ago and then they started carrying pretty much ONLY their own yarns (the I Love This ___ and the Busy Bee or whatever that ungodly priced crap is), both of which I find inferior! And then to top it all off, their prices are astronomical compared to other yarns of the same kilt. I've complained to them about it, and they just brushed off my concerns. So I'll stick with Caron Simply Soft and other brands that make quality yarns, have good customer service, and don't try to rip you off!
Okay, I'm through!
