BUY. If you can give up the softness of the drugstore brands in exchange for sustainability, then Seedling by Grove Collaborative Bamboo toilet paper should be in your bathroom. It’s cost effective and made of super fast growing bamboo, which is much kinder to the earth than cutting down trees. Plus, the packaging is all recycled paper — zero plastic.
Note that Grove Collaborative has a membership, with a generous trial period. EVEN with the cost of membership, and if you just buy TP for one person from Grove, the cost is still below average TP prices.
