I found an unopened box of the big commercial rolls at Goodwill. 12 rolls for $3. I couldn't pass it up. It's 2ply and does the job. I have had one in the bathroom the grands use and it's been in there for almost a year. It's septic safe and doesn't clog the toilet and they use a lot at one time. I have given a few rolls to friends that have RV or camper toilets. They said it works great and lasts a long time. I still have eight rolls left. It's a little peace of mind stored in the attic. LOL Thanks for the heads up about Office Depot. Forgot all about their office supplies like that.
